I know we all love a rash identification thread 
This is me, after I got out of the shower today. I have various undiagnosed allergies, mainly food. I'm off to addenbrookes to be tested next week so I've had to stop the daily antihistamine and low dose steroid I'm taking.
The last few days I've had this awful, super itchy rash after a shower. I thought it might be the shower gel, even though it's a fragrance free one so didn't use that the next day, but it still happened. Tried having the water perfect body temperature in case it was the heat, but still the same. So what, is it just water?! How on earth can I ask to be tested for a shower water allergy?!
The rash is raised on my face, neck and arms, but flat and blotchy on my chest. My palms were itchy and blotchy too, and a few little itchy hives on my stomach, back and shoulders, but the lower half of my body is almost totally unaffected. It itches like hell, and takes around 3 hours to subside. We live in a very hard water area, so may be a factor? I'm also pretty wheezy when I get out, which is the most puzzling part.
So what on earth could it be? Anyone else have a mystery post-shower rash?
