Is it all over, or contained to that area?
I had something like that once and went to see my primary care dr and he said it looked like an allergic reaction or contact dermatitis, even though I had changed nothing with food, soaps, etc
It’s in both legs and the top of one arm. I get it periodically and I have it for several hours until it goes away
Roxy does this rash itch or burn?
It itches a bit
Hmm..I ask that because my worst symptom of a flare happens to be hives although yours doesn't seem to be that...I had them for years and noone could explain it...until I was diagnosed! Hope you get answers my dear.
