Toenail Pain That Isn't an Ingrown Nail: Causes, How to Tell the Difference and Warning Signs
Toenail pain when the nail edge is not digging into the skin, there is no redness, swelling or pus, and the nail still hurts after being trimmed short is more common than people think. Medically it is grouped together as pain under or beside the nail that is not caused by an ingrown nail (painful toenail without onychocryptosis). It is not a single disease but a group of symptoms with several possible causes, ranging from subungual exostosis (a bone spur under the nail), glomus tumor, and retronychia to a condition that needs prompt diagnosis, subungual melanoma.
This article is written to help you work out which cause is most likely behind the pain, which symptoms can be watched, and which should be seen by a doctor without waiting.
Toenail pain that isn't an ingrown nail: what is it, and why is it so often misdiagnosed?
An ingrown nail is the best-known cause of toenail pain, so it becomes the first answer everyone thinks of. The problem is that when the pain does not actually come from an ingrown nail, many patients keep getting the same approach again and again: cutting the nail shorter, digging at the nail edge, applying antiseptic, or taking anti-inflammatory medicine, none of which treats the underlying cause.
The key clues that it is probably not an ingrown nail are few, and you can check them yourself at home.
The pain does not change after the nail has been trimmed shorter or allowed to grow longer.
The nail edge is not red or swollen, there is no pus, and no tissue is bulging up over the nail edge.
The pain is in one clear spot: pressing on that spot sends a sharp shooting pain, but pressing elsewhere on the same toe does not hurt.
It hurts a lot when wearing shoes, or the pain wakes you up at night.
It has lasted more than two to three months without ever fully settling.
Why this matters: some causes in this group, such as a bone spur under the nail and glomus tumor, can only be seen with specific tests like an X-ray or ultrasound, and for others, such as subungual melanoma, the outcome depends on how early the diagnosis is made. Continuing to wait and see, believing it is just an ingrown nail, has a cost.
First, tell them apart: what does an ingrown nail (onychocryptosis) feel like, and what does not fit
Description — An ingrown nail occurs when the side edge of the nail digs into the surrounding skin and causes local inflammation. The pain is at the side groove of the nail, not under the nail plate, and you can usually see red, swollen tissue bulging against the nail edge. In more advanced cases there is fluid or pus oozing and bright red tissue growing up (granulation tissue).
Causes — Cutting the nail in a deep curve at the corners, cutting it too short, wearing narrow shoes that squeeze the toes, damp feet, and naturally strongly curved nails. It is most common on the big toe.
Severity/urgency — Generally not an emergency, but if there is pus, redness spreading up the top of the foot, or the patient has diabetes or peripheral vascular problems, see a doctor promptly because of the risk of spreading infection.
When to see a doctor — When there is pus, it keeps coming back, or it has not improved within one to two weeks of self-care. Read more in our article on ingrown toenails.
In short: if the pain is at the side groove, there is red swollen tissue pressing on the nail edge, and the symptoms are linked to nail trimming, that fits an ingrown nail. But if the pain is under the nail plate, shoots when you press one spot, or occurs when the nail edge looks completely normal, think instead about the other conditions in this article.
Six quick questions to ask before seeing a doctor
Answering these six questions yourself first will help you describe your symptoms to the doctor accurately and may reduce unnecessary tests.
Where exactly does it hurt? — Under the nail plate, at the base of the nail, or at the side groove? Gently press with a fingertip or pencil tip one spot at a time and remember where it hurts most.
Does pressing one spot cause shooting pain? — If pressing one small spot causes a sharp pain that shoots through the whole toe, think of glomus tumor first.
Does cold make it hurt more? — If putting your foot in cold water clearly increases the pain, that is also characteristic of glomus tumor.
Is the nail plate pushed up or misshapen? — If the nail is lifted into a hump from underneath, think of a bone spur under the nail or another lump under the nail.
Is there any abnormal color? — Dark purple after a knock fits a blood clot under the nail, but a brown-black band that gradually widens by itself with no injury is a sign that needs to be seen by a doctor.
Is the nail still growing? — If the nail seems to have stopped growing for several months, together with a red, swollen nail base, think of retronychia.
Subungual exostosis (bone spur under the nail)
Description — A small bony growth that arises from the tip of the toe bone and pushes up under the nail plate, lifting the nail into a hump. The nail tip may separate from the nail bed, and some people see a pink fleshy lump poking out under the tip of the nail. It is most common on the big toe and is seen mostly in teenagers and young adults.
Causes — Believed to be related to repeated injury to the tip of the toe, such as impact from sports or shoes, but many patients cannot recall a clear event.
Severity/urgency — It is a non-cancerous growth, but it gradually grows larger and more painful. The main symptom is pain when wearing shoes or when anything presses on the tip of the toe. It usually does not go away on its own and does not respond to nail trimming.
When to see a doctor — When the nail is pushed up and misshapen, or the tip of the toe hurts when wearing shoes continuously for more than two to three months. Diagnosis relies on an X-ray of the toe, which clearly shows the bony growth, and the effective treatment is surgical removal of the bone by a doctor.
Subungual glomus tumor
Description — A very small tumor, usually only a few millimeters, arising from the cluster of temperature-regulating blood vessels under the nail. The classic picture is three symptoms together: severe pain that comes and goes, sharp shooting pain when one spot is pressed, and pain that worsens with cold. Some people see a faint purple or pink spot under the nail or a lengthwise groove in the nail plate.
Causes — It is a benign tumor that arises on its own. It is seen more often in women than men and more often in the fingers than the toes, but it can occur in the toes.
Severity/urgency — Not an emergency, but it is a cause that is diagnosed late, on average by several years, because the lump is so small that a routine examination cannot see it. Many patients are managed for a long time as having an ingrown nail or “nerve pain.”
When to see a doctor — When there is severe, sharp, spot-specific pain together with sensitivity to cold. The doctor may use a pointed object to find the tender spot (Love's pin test), tie off the base of the toe to see whether the pain decreases (Hildreth's test), and order an ultrasound or MRI to confirm. Treatment is surgical removal of the lump, which often relieves the pain.
Retronychia
Description — A condition in which the old nail plate stops growing forward and is pushed back into the nail base while a new nail plate grows in underneath it. The result is a red, swollen, painful nail base with occasional fluid oozing, and patients often notice that the nail has not grown longer for many months.
Causes — It often follows a knock to the tip of the foot, a sudden stop while running, or shoes that squeeze the front of the foot. It is most common on the big toe and is seen more in working-age women than in other groups.
Severity/urgency — Not dangerous, but it is very often misdiagnosed as an ingrown nail or chronic paronychia, and the treatment is completely different. Many patients are given repeated courses of antibiotics without improvement.
When to see a doctor — When the nail base is chronically swollen and painful and the nail has stopped growing. Treatment is by doctor's assessment: some patients respond to anti-inflammatory topical medicine, but clear-cut cases usually need the old nail plate removed by a doctor so that the new nail can grow normally.
Pincer nail
Description — The nail plate curves inward abnormally across its width, pinching more and more toward the tip, so that it squeezes the tissue under the nail and hurts constantly even without visible inflammation. In some people the nail curls almost into a tube.
Causes — Partly inherited, and partly following a bone spur under the nail, osteoarthritis of the toe joints, long-term wearing of shoes that squeeze the toes, or as a side effect of certain medicines.
Severity/urgency — Not an emergency, but it causes chronic pain and interferes with walking. It is often mistaken for an ingrown nail because the pain is also at the nail edge. The difference is that a pincer nail hurts because of the squeezing shape of the nail, not because the nail edge is digging into the skin.
When to see a doctor — When the nail shape is clearly abnormal and the pain affects walking. The doctor will assess whether an underlying cause such as a bone spur under the nail is also present before planning treatment.
Paronychia: acute and chronic forms do not hurt the same way
Description — Inflammation of the tissue around the nail. The acute form is red, swollen and warm with throbbing pain, and usually has pus within a few days. The chronic form has soft swelling at the nail base, rarely has pus, causes a dull ache lasting months, and the cuticle at the nail base is lost.
Causes — The acute form is usually caused by bacteria after a small wound from picking or cutting the skin around the nail. The chronic form is linked to repeated contact with water and irritants, and to Candida yeast.
Severity/urgency — Acute paronychia with pus should be treated promptly because it may need to be drained. The chronic form is not urgent but takes a long time to treat.
When to see a doctor — When there is pus, the pain gets worse every day, there is a fever, or it lasts longer than six weeks. Details of both forms are in our article on paronychia.
Subungual hematoma (blood under the nail): throbbing pain after a knock or a run
Description — Blood collects under the nail plate and appears dark red, purple or black. The pain is throbbing in time with the pulse and is usually worst in the first 24 to 48 hours, then gradually eases. An important clue is that the discoloration moves out toward the tip of the nail as the nail grows.
Causes — Something falling on the foot, kicking something hard, or repeated pressure in long-distance runners and athletes who have to brake suddenly. The latter is sometimes called runner's toenail.
Severity/urgency — If the blood covers more than half of the nail plate, the pain is severe, or a broken toe bone is suspected, see a doctor within 24 to 48 hours, because draining the blood by a doctor within this period can relieve the pain. Do not pierce the nail yourself with a needle or a hot object because of the risk of infection.
When to see a doctor — When the pain is severe, when you cannot recall any knock at all, or when the dark discoloration does not move out and does not fade within two to three months. How to tell a hematoma from cancer under the nail is explained in detail in our article on black nails and their causes.
Subungual wart
Description — A rough-surfaced lump under the edge of the nail or around the nail that is painful when pressed. It may push the nail plate up or make the nail edge chipped. Some people see tiny black dots scattered within the lump, which are small capillaries with blood clots.
Causes — Human papillomavirus (HPV), which spreads by contact and can pass to other fingers through picking or biting the nails.
Severity/urgency — Not dangerous, but harder to treat than warts elsewhere because it lies under the nail plate, and it can come back.
When to see a doctor — When the lump grows, hurts, deforms the nail, or does not go away with self-treatment. A doctor should assess it, because some lesions under the nail look like warts but are not.
Nail fungus (onychomycosis) thick enough to be painful to press
Description — The nail becomes thick, brittle and crumbly, cloudy yellow or brown in color, with debris collecting under the nail. Normally nail fungus does not cause pain, but when the nail becomes so thick that shoes press on it, or when a misshapen nail presses on the tissue beneath it, it can hurt.
Causes — Mainly dermatophyte fungi. Risk factors are dampness, very sweaty feet, diabetes, a weakened immune system, and use of public bathrooms or swimming pools.
Severity/urgency — Not an emergency, but in people with diabetes or narrowed peripheral arteries, a thick, cracked nail is an entry point for bacteria and should be looked after.
When to see a doctor — Before starting any medicine, have a doctor confirm that it really is a fungus with a laboratory test, because thick, misshapen nails can also be caused by psoriasis and other conditions. Details are in our article on nail fungus.
Digital myxoid cyst
Description — A clear or flesh-colored dome-shaped lump on the upper part of the nail base, usually no more than one centimeter, that may cause a dull ache when pressed. A helpful diagnostic clue is a lengthwise groove in the nail that lines up exactly with the lump, because the lump presses on the nail-forming area.
Causes — Linked to osteoarthritis of the last finger or toe joint and to joint fluid leaking out and collecting. It is seen more in older people than in younger adults.
Severity/urgency — Not dangerous, but it should not be pierced or squeezed by yourself, because it has a connection to the joint. Piercing it yourself risks introducing infection into the joint, which is a serious condition.
When to see a doctor — When the lump grows, hurts, leaks clear fluid, or deforms the nail. Grooves or waves in the nail plate have several possible causes, explained in our article on wavy nails.
Pain from shoes and repeated pressure: why runners and high-heel wearers get big toe pain
Description — A dull ache at the tip of the toe or under the nail after long walks or runs. There may also be a darkened nail, a thickened nail, or callus under the tip of the nail. The symptoms usually improve with rest and a change of shoes.
Causes — Shoes that are too narrow or too short so that the toe tips repeatedly hit the front of the shoe, high heels that greatly increase pressure on the front of the foot, running downhill and sudden braking in sports that involve changes of direction, and socks that squeeze the front of the foot.
Severity/urgency — Not dangerous, but it is the cause that is easiest to fix and the one most often overlooked. Before going on to complicated tests, always check your shoes first.
Basic self-care
Choose shoes with enough room at the front of the foot. The longest toe should be about one centimeter away from the front of the shoe.
Measure your feet in the afternoon or evening, when feet are at their largest during the day.
Trim toenails straight across, without a deep curve at the corners and not so short that the flesh under the tip of the nail shows.
Temporarily cut down on running distance when pain begins, rather than pushing on at the same pace.
When to see a doctor — When pain continues for more than two to four weeks after adjusting your shoes and resting.
When the pain doesn't come from the nail: diabetic foot, narrowed blood vessels and nerves
Description — Pain or burning at the tip of the foot while the nail and skin look normal. There may be numbness, tingling, or a pins-and-needles feeling, together with dry foot skin, thinning hair on the shins, or slow-healing wounds.
Causes — Nerve damage from diabetes (diabetic neuropathy), narrowing of the arteries in the limbs (peripheral arterial disease), nerve compression at the ankle, and deficiency of certain vitamins.
Severity/urgency — This group matters most in terms of long-term outcomes. Diabetic patients with numbness may not feel pain in proportion to the real severity, so wounds can spread without being noticed.
When to see a doctor — When there is numbness or burning, when you have diabetes and any foot symptom at all, or when the tip of the foot hurts at night and improves when the leg is hung down, which is typical of narrowed blood vessels. This group should be examined without waiting.
Warning signs that need a doctor, including subungual melanoma
The following symptoms should not be left to watch on your own.
A brown or black lengthwise band on the nail that gradually widens, darkens, or has an irregular edge, with no history of a knock, is a reason to be checked for subungual melanoma.
Dark color spreading out onto the skin around the nail or onto the cuticle, which is called Hutchinson's sign.
A single nail that becomes misshapen, chipped or falls off for no reason, especially when it affects one side only and there was no accident.
A lump that grows fast, bleeds easily, or a chronic sore under the nail that does not heal within one month.
Redness and swelling spreading up the top of the foot, fever, or pus draining, which point to a spreading infection.
Pain so severe you cannot walk, or pain that wakes you in the middle of the night every night.
People with diabetes, an impaired immune system or peripheral vascular problems who have any toenail pain.
Remember that subungual melanoma is uncommon, but it occurs most often on the big toe and the thumb, and in Asian people the proportion of melanoma arising on the palms, soles and under the nails is higher than in white people. A changing band of color should therefore always be assessed.
What does the doctor check when you come with toenail pain?
A detailed history — How long it has hurt, what kind of pain, whether it is related to cold or shoes, whether an injury came first, whether the nail is still growing, and any underlying diseases, especially diabetes.
Physical examination and pressing to find the tender spot — Identifying whether the pain is under the nail plate, at the nail base, or at the side groove, and examining both feet to compare them.
Examining the nail with a dermatoscope (dermoscopy) — Helps tell blood clots from melanin pigment and helps assess lengthwise color bands.
Specific tests — Pressing a spot with a pointed object and tying off the base of the toe when a glomus tumor is suspected.
Imaging — An X-ray of the toe when a bone spur under the nail or a fracture is suspected, and an ultrasound or MRI when a soft tissue lump is suspected.
Laboratory tests — Nail scrapings sent for fungal testing when a fungus is suspected, and a biopsy when a lesion needs a confirmed diagnosis.
Not every test is done in every person. The doctor chooses according to the symptoms assessed in each case.
How is it treated according to the cause, and how much can you do at home?
The principle is to treat the cause, not just the pain. A summary by condition follows.
Bone spur under the nail — Surgical removal of the bone by a doctor. Trimming the nail or applying medicine does not help.
Glomus tumor — Surgical removal of the lump, which often clearly relieves the pain.
Retronychia — Assessment by a doctor. Some patients use anti-inflammatory topical medicine, and clear-cut cases usually need the old nail plate removed.
Pincer nail — First assess for an underlying cause, then choose a method to reshape the nail or surgery as appropriate.
Paronychia — The acute form with pus may need draining and antibiotics as prescribed by a doctor. The chronic form focuses on avoiding water and irritants together with topical medicine chosen by the doctor.
Subungual hematoma — In patients with severe pain who come early, the doctor may drain the blood. For those with less pain, treatment is supportive and the color is monitored.
Nail fungus — Confirm the diagnosis first, then use topical or oral medicine according to severity under a doctor's supervision, because oral medicine requires consideration of effects on the liver and drug interactions.
Causes from shoes and pressure — Adjust shoes, temporarily reduce high-impact activity, and trim nails correctly.
What you can safely do yourself while waiting to see a doctor
Soak the foot in clean water at room temperature to slightly warm for 10 to 15 minutes a day, then dry it completely.
Switch temporarily to wide-fronted shoes or sandals that do not press on the toe tips.
Trim nails straight across, do not dig at the nail corners, and do not cut the skin around the nail.
You may use paracetamol for pain at the dose on the label if you have no contraindication.
What not to do
Do not pierce the nail yourself with a needle, a hot object or a paper clip.
Do not remove the nail yourself, and do not let anyone who is not a health professional remove it for you.
Do not use leftover antibiotics from a previous illness on your own.
Do not squeeze or pierce a cyst at the nail base yourself.
FAQ: common questions about toenail pain
Why does my nail suddenly hurt?
Nail pain that arises on its own, with no injury beforehand, usually comes from three main groups. The first is cumulative pressure from shoes, which is the most common and usually improves when shoes are changed. The second is inflammation or infection around the nail, which shows visible redness and swelling. The third is a lump or lesion under the nail such as a bone spur under the nail or a glomus tumor, which usually hurts at one spot and is chronic. If the pain continues for more than two to three weeks with no sign of improving, a doctor should examine it to identify the cause.
What can cause a sharp, stabbing pain in the nail?
A sharp, shooting pain at one spot is different from a dull ache across the whole toe, and it is the pattern that makes doctors think of a subungual glomus tumor first, especially when pressing one small spot hurts a lot and the pain gets worse with cold. Other causes of this kind of pain are a compressed or degenerating nerve and early acute inflammation around the nail. Telling them apart requires a physical examination, together with an X-ray or ultrasound in some cases.
What can cause toenail pain without an ingrown nail?
When the nail edge is not digging into the skin, the common causes in order of likelihood are pressure from shoes and repeated use, blood under the nail from a knock that you cannot remember, retronychia that makes the nail stop growing, a pincer nail whose shape squeezes the flesh, a bone spur under the nail, glomus tumor, a wart under the nail, and nail fungus thick enough to be pressed on. There are also causes where the pain does not come from the nail itself, such as diabetic neuropathy and narrowed peripheral blood vessels.
Why does my toenail hurt when I press on it?
The spot that hurts when pressed says a lot about the cause. If it hurts when you press the side groove and the flesh looks red and swollen, it is usually an ingrown nail or paronychia. If it hurts when you press the nail base and the nail is not getting longer, think of retronychia. If pressing one small spot under the nail plate causes shooting pain, think of glomus tumor. And if it hurts when you press the tip of the nail and the nail is pushed up into a hump, think of a bone spur under the nail. Gently pressing one spot at a time and noting where it hurts will help the doctor a great deal on the day of the visit.
Why does my toenail throb?
Throbbing in time with the pulse points to pressure building up under the nail or to acute inflammation. Two common causes are blood under the nail after a knock and acute paronychia that is about to form pus. Both should be assessed by a doctor within one to two days if the pain is severe, because draining the pressure or the pus by a doctor relieves the pain, and you should not pierce it yourself because of the risk of infection.
What nail changes suggest cancer?
The features that need a doctor's examination are a brown or black lengthwise band on the nail that gradually widens or darkens by itself, a band with an irregular edge or uneven color, involvement of a single nail with no history of a knock, dark color spreading onto the skin around the nail, or a misshapen, cracked or chipped nail together with a chronic sore or a lump that bleeds easily. A practical way to tell the difference is that a mark from blood under the nail moves out toward the nail tip and fades as the nail grows, whereas a mark from pigment stays in place. If you are not sure, have a dermatologist examine it with a dermatoscope rather than waiting and watching.
Summary
Toenail pain that is not an ingrown nail is not a minor matter, and it is not a single disease. Three questions help with a first sorting: where does it hurt, does pressing one spot cause shooting pain, and is the nail still growing? Most causes are not dangerous and can be corrected, especially those from shoes and pressure, but some need specific tests and treatment by a doctor, and certain features, especially a changing lengthwise color band, need assessment without waiting.
If the pain continues for more than two to three weeks, does not improve after adjusting your shoes, or you have any of the warning signs in this article, see a dermatologist for diagnosis. Treatment that targets the cause from the start reduces the time you have to put up with unnecessary pain.
