Nail surgeries can be required to treat deformities or for nail removal to address an injury or infection in the nail bed. Ingrown nails are a common problem resulting from either growth of nail fold inwards into the nail bed or abnormal embedding of the nail plate into the nail groove, causing significant discomfort. Toenail fungus is an infection that gets in through cracks in your nail or cuts in your skin. It can make your toenail change colour or get thicker. It can also hurt. Left untreated, an infection could spread to other toenails, skin, or even your fingernails.
