Ingrown toenails (IGTN’s) occur when a nail spicule or edge of the nail pierces the skin and causes a bacterial infection.
They are a very common reason for people to visit a podiatrist, as they can be very painful and normally do not resolve without removal of the aggravating nail spicule or jagged edge.
Permanent ingrown toenail surgery is necessary if IGTN’s are recurrent, or very severe.
