Nails may hurt due to an infection, nail biting, injury, or other causes. Treatment depends on the cause and may involve home remedies and medical treatments.
Nail pain may be due to temporary issues like injuries and irritation. It may resolve without medical treatment.
However, it’s important to contact a doctor for advice if pain is severe or if it keeps returning. Your doctor can determine the underlying cause and advise on suitable treatments.
Read on to learn more about what can cause sore fingernails or toenails, including possible causes of pain by location, and how to treat nail pain.
There are numerous possible causes of fingernail or toenail pain,
Nail infection (paronychia)
One common cause of nail pain is a paronychia, or a nail infection. In addition to pain, nail infections
Nail infections may also cause the nail to thicken, and pus to drain from around the nail.
Fingernails and toenails are most often infected when bacteria enters an injury on the cuticle, nail bed, or finger. Nail infections can be serious, and in some cases require medical attention.
Fungal nail infection
When a fungus enters an injury on, under, or around the nail, a fungal nail infection can arise. In most cases, fungal nail infections are caused by the same fungus that causes athlete’s foot.
Other fungi, including yeasts and molds, can also affect the nails.
In addition to causing pain, fungus can make nails turn yellow or white. Other symptoms of a fungal nail infection include:
- nail thickening
- crumbling
- splitting
- separation from the skin
Without treatment, a fungal nail infection can spread to other nails and to the skin, in rare cases causing permanent damage to the nail bed.
Ingrown nail
Ingrown nails cause the sides of the nail to curve into the skin. This painful condition can develop when nails are trimmed improperly, after an injury to the nail, or when a person wears shoes that are too short or tight.
Ingrown nails most commonly affect the big toe. However, it can affect any toenail.
Signs of ingrown nails include:
- swelling
- tenderness
- pain
- redness or discoloration
- soreness
- infection
Hangnail
Hangnails are not actually nails, but pieces of skin that tear off the edge of your nail.
Hangnails are a type of painful nail condition with a variety of possible causes, including:
- nail biting
- dry skin
- irritating soaps
- cold temperatures
Hangnails might bleed. It’s important not to rip off hangnails, as doing so puts you at risk of an infection.
Physical injury
While nails are strong, it’s possible to injure them when something heavy falls on them or when they get caught in a door.
These injuries are usually painful, because there are many nerves under and around the nails.
Sometimes, a physical injury to the nail causes bruising or bleeding under the nail, known as a subungual hematoma. The nail may also fall off before it regrows. A bruised nail may feel tender as it heals.
Nail biting
Nail biting can cause pain, and it may damage tissue that helps nails to grow.
Nail biting, which includes biting the skin around the nail, and the cuticle, also increases the risk of nail infections.
Usually, stopping biting nails is enough to stop the painful symptoms it causes. You may require medical treatment if an infection develops.

It can be helpful to take your own clippers and other nail tools to the salon to avoid exposure to bacteria or fungus carried on others’ nails.
Nail polish and nail polish remover contain chemicals that may damage the skin around the nails.
When painting your nails or removing polish, try to only work on your nails. Avoid getting polish and remover under your nails, on your cuticles, and on your fingers.
Using natural nail polishes and removers, and regularly moisturizing your hands, may help reduce discomfort.
The process of applying acrylic nails can cause damage to the nail, leading to pain.
In most cases, those who prepare to apply acrylic nails begin by cutting down the cuticle of the nail, and filing down the nail. This leaves the nail prone to infections.
Additionally, gluing on nail extensions and adding acrylic can cause irritation and dryness, leading to hangnails, ingrown nails, and nail deformities.
Less damaging alternatives to acrylic nails include gel nail extensions and dip powder.
Ways to manage or treat nail pain can depend on the underlying cause.
Hangnails, physical injuries, and nail biting
For nail pain caused by most hangnails, physical injuries, and nail biting, the best treatment is to leave your nails alone.
Avoid ripping off hangnails and allow them to grow out. Maintaining good nail hygiene by cleaning and trimming nails regularly is important.
If you have a severe injury to the nail, or if there is a lot of bleeding, it’s best to seek medical advice. It’s possible that the finger or toe may be broken.
Ingrown nails
You can treat ingrown nails and related pain by:
- soaking your hands or feet in warm water 3 to 4 times per day
- wearing footwear that does not pinch your toes if the toenail is ingrown
- taking pain relief medication
You may require medical treatments, such as antibiotics, if the nail becomes infected. Surgery may be necessary to remove part or all of the nail.
Nail infections

Nail pain may develop due to a nail infection, ingrown nails, or injury to the nail. Nail biting and hangnails can also cause sore fingernails or toenails.
