Ingrown nails, also known as onychocryptosis, is a common condition in which the edges of the nail grow into the surrounding skin, causing pain, redness, swelling, and sometimes infection. This can occur when the nail is cut too short, causing the edge to dig into the skin, or when the nail is curved and grows into the skin at the sides. Ingrown nails can be treated with home remedies such as soaking the affected area in warm water, applying antibiotic ointment, and using over-the-counter pain medication. In more severe cases, a doctor may need to perform a procedure to remove the affected portion of the nail or to remove the entire nail.
