Yellow/Hole in Fingernail
Hello, I had a bump and some discoloration in about 1/3 of my thumbnail for some time now. I just assumed since it started in the middle of the nail that it would grow out. No pain or anything. But now about 1/2 of that 1/3 just up and fell out revealing the nail bed with the remaining part discolored a bright white (vertical). Any ideas?
