I have no official diagnosis of celiac disease, but I experience symptoms similar to it. However, I'm not brave enough to have an intestinal biopsy. I haven't been adhering to a strict gluten free diet due to a lack of confirmation. I have a family history of Crohn's disease, which seems to be linked to Celiac disease. I had a celiac blood test, which came back negative. Even if I do not have celiac disease, it seems like I do have an intestinal problem of some kind. I also have typical symptoms of an autoimmune disorder, and I know that consuming wheat/gluten products makes me ill.
Recently I've had rashes on the back of my legs. For about two months it comes and goes, in the same area. I took pictures when it was the worst I've seen. I've never experienced this degree of a rash before, but I've always had red bumps form randomly on my chest, back and arms.
I recently read about Dermatitis Herpetiformis and it's connection to celiac disease. I would like to know opinions of anybody experienced with this, if this rash could possibly be that. I don't experience much itchiness however, which I read is a symptom of DH. Sorry, the images are ugly.
