I am 23years old, 5ft 4inch, 7stones 8lbs, I have on and off issues with my iron level however I am not aneamic. I had low vitamin b a year ago and had 6 injections and I have not had a problem since. About 4months ago I got ringworms which I think I caught from the swimming pool. After 8weeks these went. A couple of months back I started getting these dry raised patches on my face which would be bumpy and go white patches after a few days. Now I have so many white patches on my face. They start of dry, they become raised, sometimes itchy and burn my skin and then turn white. What could this be?
