My husband has a reoccurring rash, that itches ,turns red, and is very warm to the touch and swells up. Went to immediate care last week was given cream and told to take Benadryl. The rash moves from different areas. And it s pealing. Any suggestions? My husband has just finished and 6 wk treatment for bladder cancer, but that was 3 weeks ago, and the rash just started last week. It shouldn t of come from that? It s the not change in his life, no meds ,soaps, food.
