I am having a variety of different skin problems over the past year like, teenage acne, constant skin dryness, all over apart from face . Small itchy rash just on my back making my skin so dry it itches more than chicken pox, something that looks like ring worm but is not although it started in a ring with bumps surrounding it the ring has expanded the skin inside the ring has gone darker than my skin like greyish it sometimes itches but i dont know if that is just me getting hot and also i have the same thing in other places you cant catch it otherwise my hubby would have it the bumps have flattened somewhat. Has anyone else had this or something like this ??????
