I've been diagnosed with Celiac & DH since October, 2005. Your description describes where I was with my case some 6 years ago. The itching would go and come--disappearing for months at a time. My doctor(s) initially thought I was have a reaction to something in my environment. I also developed severe acne on my face, which was wild because I never had acne as a teenager. Then I was told I had Rosacea. I eventually started have patches break out in different places: both elbows, both ears, and especially my female area. After about 4 years I started experiencing a fiery, blistery rash in a circular patch on the outside of my thigh. The itching became so horrific at times I thought I'd go mad--scratching until I bled. At other times it was just a constant irritation. The patches would show up for months at a time and then completely disappear. The outbreak areas were not always constant and of course the severity fluctuated. I was treated for 2 years by a dermatologist before I was diagnosed with Celiac. After the Celiac diagnosis the dermatologist finally tested me for DH. Once I started with the gluten-free diet all of the break out area improved. However, after being gluten-free from 6 months, I started having additional area of breakout. the spots are usually now all over my face, my elbows and sprinkled all over my back. I've been on Dapsone for short spurts (less than a month) three times in the past 16 months. I've always had quick respose to Dapsone with my spots usually disappearing within a few days.
