After having these rashes on my body for many months, using different prescribed medication, it was discovered that I have Celiac Disease which Dermatitis Hepitiformis is a complication of.
I stopped eating gluten and trying to avoid all contamination, which makes it hard to participate in any function where food is served.
I still get some flare-up of the rashes but I am always trying to avoid any wheat, barley and oats products. I even had to change shampoo, toothpaste and so many other items that should be normal to use to any other people.
