It looked like a wart because it was the same color as my skin and it was there for like 8 months - than out of the blue one day it started to hurt a little so i felt it and it was a little bigger and it looked like a white head - than when i woke up in the morning it looked like kind of black and purple - then i decided to wash it in the shower and when i got out it was almost like i popped it???? does any one know what this is???
