In the last two weeks, our daughter has presented with itchy blisters on her legs that broke open, got progressively larger and more angry looking, and now look like open sores. Of course, our new doc (we moved last summer), says it may be impetigo. I insisted that she be tested for DH, but he wanted to give it a week of treatment and go from there. I said I didn't want to wait a week. So we are moving ahead with the antibiotics in case they are infected, and I take her back in in a few days for the skin biopsy. Personally, with our family history, I prefer to rule out celiac before we run the gamut of every other condition it COULD BE! He was not as convinced, obviously, but reluctantly agreed to what I wanted.
That's a long story just to say "go with your gut!" Even with just a little bit of research on celiac disease, it's hard to not to see every symptom as related. I share your obsession Happy!
