I'm 21, male. On and off for about four years now, after every time I take a shower and dry off, I itch unbearably on my lower legs, arms, back, and sometimes chest. There is no rash or skin irritation. I have changed soaps, shampoo's, and my methods of washing and drying myself to try to make a difference, but nothing works. I once heard some pregnant women itch after contact with hot water due to a vitamin deficiency. Could I have a similar problem? Any suggestions?
