Symptoms: An ingrown toenail occurs when the toenail curves down into the surrounding flesh instead of growing out over the top of your toe.

Prevention: Cutting toenails straight across instead of rounding them off. Wearing shoes and socks that fit properly.
Diabetics are also affected by ingrown toenails due to poor circulation.

Treatment:If your toe isn't too swollen, and the nail hasn't burrowed into the flesh yet, it may be possible to treat it yourself. You'll do this by trying to guide the nail past the area into which it's curving. Once the nail has dug deeper into the flesh, though, it's best to go to a podiatrist. If the surrounding area is red and inflamed or oozing pus, don't try to cut the nail out yourself--you won't be able to cut it as well as your doctor can, and the possibility of an untreated infection is too great a risk.

Surgery may also be needed to remove the nail and or skin surrounding the nail.
