About two years ago I joined a X-country team and while I was running I injured both my toenails causing them to fall. One successfully grew correctly, but the other one is still trying to grow.. I don't know if it'll grow back like it used to. Part of the nail bed is dry and there seems to be some kind of nail growth but hasn't completely grown right. It's only grown halfway and it's been like that for months now. When I press on the nail it kind of hurts. Is this an infection? How can I make it grow back to the way it used to be??? Help!!!
