An ingrown toenail is when the nail grows into the flesh instead of on top of it. Ouch. They are super painful and can cause bad infections if not taken care of reasonably quickly. If an infection is left untreated for too long it can get into the bone and cause serious problems. Sometimes Foot & Ankle Specialists of Nashville will just trim back the ingrowing part of the nail. However, they tend to re-occur in most people who suffer from them so usually Foot & Ankle Specialists of Nashville will permanently remove the ingrowing part of the nail so that it won't grow back. The toe is numbed (of course!) so most people find lots of relief from having the nail removed.
