I've had the same problem with outbreaks in that area. Dermatitis Herpetiformis is pressure sensitive. Any place where there's pressure on the skin can cause a dermatitis herpetiformis sore to occur.
I've had dermatitis herpetiformis blister on my fingers where I hold my pen and my knitting needles. I've developed dermatitis herpetiformis on the palms of my hands after pushing a shopping cart around. Same for outbreaks in the crotch area where seams of pants come together, fabric wads up and elastic in underwear rubs (including under elastic bra bands).
Avoiding foods high in Iodine helps, but the most help I found is to supplement with Niacin Vitamin B 3 (and a B Complex because the B's all work together). I get Niacin in the form that flushes (nicotinic acid - not the same as nicotine in tobacco). The flushing of Niacin helps clear the tTg 3 IgA deposits out of the skin. (tTg 2 IgA is what blood tests for Celiac Disease measure). Niacin really helps heal and improve skin health.
I'm hypersensitive to adhesives, bandages, etc. Niacin helps make the skin integrity stronger.
Hope this helps!
Would you mind sharing the brand of Niacin you use? I’m trying to do my research but I was just diagnosed and making sure it’s gluten free and the correct formulation has me about in tears.
