Toenails that curl in on the sides can be a sign of several underlying conditions. In this article, we will discuss the most common reasons for curled toenails, their symptoms, and treatment options.
Ingrown toenails
Ingrown toenails are a common condition that occurs when the toenail grows into the skin on the sides of the toe. This condition often affects the big toe and can cause pain, swelling, and redness. In severe cases, it can lead to infection.
Symptoms of an ingrown toenail include:
- Pain and tenderness along the side of the toenail
- Redness and swelling around the toenail
- Pus or drainage around the toenail
- Difficulty walking or wearing shoes
Ingrown toenails can be caused by several factors, including:
- Incorrectly trimming toenails
- Wearing shoes that are too tight or narrow
- Trauma to the toenail
- Genetics
Treatment for ingrown toenails depends on the severity of the condition. Mild cases may be treated with warm water soaks, antibiotics, or over-the-counter pain medication. More severe cases may require surgical removal of the toenail or a procedure to remove the ingrown portion of the nail.
Fungal toenail infection
A fungal toenail infection, also known as onychomycosis, is a common condition that affects toenails. This condition is caused by a fungus that grows under the toenail, causing it to become thickened, discolored, and brittle.
Symptoms of a fungal toenail infection include:
- Thickened toenails
- Discolored toenails (yellow, brown, or white)
- Brittle toenails that may break easily
- Foul odor
- Debris under the toenail
Fungal toenail infections can be caused by several factors, including:
- Poor hygiene
- Walking barefoot in public places such as locker rooms and swimming pools
- Wearing shoes that don’t allow air to circulate around the feet
- Diabetes
Treatment for fungal toenail infections may include oral or topical antifungal medication, laser treatment, or surgical removal of the infected toenail.
Hammer toes
Hammer toes are a condition that occurs when the toe becomes bent at the middle joint, causing the toe to curl downwards. This condition can be caused by several factors, including:
- Wearing shoes that are too tight or narrow
- Genetics
- Trauma to the toe
- Arthritis
Symptoms of hammer toes include:
- Pain and tenderness in the affected toe
- Difficulty walking or wearing shoes
- Corns or calluses on the affected toe
- Redness and swelling around the affected toe
Treatment for hammer toes may include wearing special shoes or inserts that help to straighten the toe, physical therapy, or surgery.
Toe injuries
Toe injuries, such as stubbing your toe or dropping something on your foot, can cause the toenail to curl in on the sides. This can be a temporary condition that resolves on its own, or it can lead to a more severe condition such as an ingrown toenail or fungal toenail infection.
Symptoms of a toe injury include:
- Pain and tenderness in the affected toe
- Swelling and redness around the affected toe
- Bruising around the affected toe
- Difficulty walking or wearing shoes
Treatment for a toe injury depends on the severity of the injury. Mild injuries may be treated with rest, ice, compression, and elevation (RICE). More severe injuries may require medical attention, such as casting or surgery.
Conclusion
Toenails that curl in on the sides can be a sign of several underlying conditions, including ingrown toenails, fungal toenail infections, hammer toes, and toe injuries.
