Also known as onychocryptosis, occurs when the edge or corner of a toenail grows into the surrounding skin instead of over it. This can lead to pain, swelling, redness, and sometimes infection. Ingrown toenails most commonly affect the big toe, but they can occur on any toe.

Ingrown toenail surgery (Partial Nail Avulsion or Total Nail Avulsion), is a medical procedure to address severe or persistent ingrown toenails. It involves removing the problematic nail section and, at times, a part of the underlying nail bed. It is deemed safe and effective when conservative treatments fail and is typically performed in a clinical setting. Recovery time varies based on the individual and the extent of the surgery.
