Hi, I have 3 questions to ask but first the problem. So the problem is my left foot second toe nail which is the long toe, it's color is black but not fully black and it?s currently wanting to break. So my first question is should I take it out myself or just leave it and it will take it out by itself? The second question is will it grow back again, if so how long will it take to grow? The last question is when my long toe does?t have a toe nail or it's growing, can I play sports like basketball?
