What Is An Ingrown Toenail?

Ingrown toenails occur when bacteria gets trapped between your toenail and skin, usually near the borders of the toenail.  This causes a localized infection to occur which results in pain, swelling, redness and increased warmth.  There does appear to be a hereditary component to the development of ingrown toenails but, trauma, improper trimming and poor fitting shoes can contribute to the development as well.
