I woke up with rash over my back, chest, stomack and hips. Top part of thighs too and back of thighs rash hurts from sitting too long. It seems evenly spread, but I have no idea what happened. My skin feels extremely dry too and I have not put lotion on worrying it will make it worse or irratate. I m going on the second night, third day. I am taking Benadryl at night, but no difference in two days. I have not changed detergents, soaps, or eaten anything different from the normal. I m a healthy eater too.
