I have been experiencing a strange rash on my upper body for almost a year. It seems to flare up with exercise or heat exposure and showering. But also in general it calms down at times but never goes away...it looks and feels awful. had blood work done but nothing popped up. Because of my Insurance I have been on a waiting list to see an Allergist. I have seen a Dermatologist ones and all he did was prescribe cortisone cream, which did not help. Also at night in bed my skin feels really hot and dry and uncomfortable. I am a 47 year old female, in great health and teach yoga and work as a massage therapist. I cut out Gluten a few month ago but that did not help ;-(
