I am surprised that your doctor would not diagnose based on sight? I was diagnosed with dermatitis herpetiformis but the biopsy came back negative. The dermatologist said that can happen as the disease was not active at the time, but it was classic dermatitis herpetiformis in his opinion especially since I was already diagnosed with celiac several years prior to the dermatitis herpetiformis flare up. Like many on the dermatitis herpetiformis threads I suffered from itchy burning lesions on my elbows. Very painful when I was in the shower. Dermatologist prescribed dapsone gel 7.5%. There is a pill option but I wanted to first try the topical gel and it eased the burning sensation and after a few weeks got rid of the visible signs of dermatitis herpetiformis. I only use it when my dermatitis herpetiformis is active. I recently had a flare up but had the dapsone gel available and it quickly eased the itchy burning skin on both elbows (which is where I usually get dermatitis herpetiformis). I was also told to avoid iodine and of course gluten.

I have celiac and I have been gluten free for several years. Very careful and as far as I know I have never consumed gluten. Recently my bowel movements changed dramatically and I have been Bristol 6 for two months and just now moving to Bristol 5. My GI ran all sorts of blood tests and all were good. The celiac panel test for tTG IgA came back at 13.6 (normal <15). My GI said that is normal. Is that normal for someone on a gluten free diet? I am wondering if I did Ingest gluten and the Bristol 6 stools, the abdominal pain, and nausea are all a result of eating gluten. The GI does not think so since I was at 13.6...or in his words "normal". He wants to do endoscopy, biopsy, colonoscopy, because he is concerned it may be something more serious. Could this just be a case of gluten "poisoning"? I feel like my bowel movements are slowly normalizing but still having some issues.

This article has some detailed information on how to be 100% gluten-free, so it may be helpful (be sure to also read the comments section.):    

Great! Just what I was looking for.  Thanks, Scott.
