My wife has a rash on her hands that will not go away. She works at a hospital and wears latex free gloves. She also washes her hands constantly. This started once before and we realized she has an allergey to latex. Her hands are covered with a red rash covered with rough skin and bumps. Her hands itch and burn and hurt constantly. She has switched hand sanitizer, soaps and gloves and the rash burns more and continue to get worse. Lotions will not help, they just burn (which i believe is due to the open sores that scratching has caused.) She is pregnant, has had chicken pox. What could cause this.
