Cutting toenails too short (or growing them too long) and wearing shoes or socks that are too tight can cause painful ingrown toenails. Soaking the affected foot and removing pressure from the toe can help speed healing. See your doctor if there are signs of infection or if the toenail does not improve.

Abnormal changes in nail morphology can be considered a basis to support the diagnosis of certain systemic or dermatological diseases. Nail diseases can be classified as localized nail diseases, diseases due to congenital or genetic defects, nail diseases associated with systemic diseases or widespread skin diseases.

Ingrown toenails that dig into the flesh and cause pain are common conditions that many people experience, and can be treated at home. However, some severe cases require medical attention to avoid serious complications, especially in people with diabetes or other conditions that cause poor blood circulation.
