Today I got this horrible rash on my arm.. Didn't hurt or anything just hot and uncomfortable.. I got it the other night on my lower leg and when I went to the doctor they wanted to test me for chlamydia, which didn't make since to me.. I've been really really sick with Lymes disease and in treatment and I was thinking this was more of a detox thing on my skin.. I said no to the test cause I'm having no symptoms and the rash goes away after about an hour.. I'm wondering if it could be an allergic reaction to something? Any Ideas?!
