I have had this thing on my left foot thumb, it was just a simple thing, I wore in a little tight shoes & there was some infection you could call it, so I applied some betadine, figured it would heal up. At first I didn't notice my left foot thumb nail had messed up, but still i figured after applying some more betadine it should heal up. and Now the nail has healed up and I noticed that perhaps the skin had come above the nail on the left side of the thumb and it hurts when I putron pressure, I can't wear shows or anything, there is still some healing left and moreover it is somewhat swollen on the left side only. I don't know what to do ?
