Some news. I did endoscopy / coloscopy because i feel very very bad with gluten (chronic diarrhea, fatigue, muscles pain, headaches..).
There is no villous atrophy, just an unknown mild inflammation of duodenum, and presence of lymphoid germinal center.
I'm sure i'm definitely very sensitivite or delayed allergic (the same thing?) to gluten. A little amount of gluten give me symptoms (piece of bread, tomato sauce with wheat starch or even rice krispies!)
Since i'm on gluten free diet, my skin problems have decreased a lot, as you can see on these pics :
That's strange because the rashes sounded like DH : a kind of insect bites with fluid inside, and the rashes were symetric around the mouth. The only thing (and the most important) thats differs is the lack of itching/burning.
