I do get a strange rash every day after a warm/hot shower around the edges of my arm pits that last a few minutes and then goes away. It does itch during those few minutes. At first I thought it was the towels but tested that theory and it wasn’t. This has been going on for years. Other than that I don’t have any other rashes or bumps.
Can I assume you also have dermatographia (skin-writing)? Are you taking any antihistamines? Thanks so much! We’ll figure this out! 😉
