I was eatin a blueberry bar when my ankle became itchy then my thigh now my wrist so I stopped eating the bar(just now I have about 1/4 of it left) I don't always breakout to these.
I found some Cortizone 10 but next time if I'm not so lucky to find some.
I think maybe when I get these rashes it is a build up cause i don't get them often.
its probably from the gluten because I used to breakout everyday from eating gluten but then I didn't. I'll make sure to carry some benedryl too maybe that will help as well.
