I suffered with rashes on my elbows knees and has of spine for years. The itching was intense and made me totally miserable. Rash started as large blisters which eventually popped and scabbed over.. Doctor prescribed every cream known to man and none worked. In the end I saw a new doctor who knew immediately what it was. One visit to the hospital and biopsies on the rash area revealed DH. I am registered Coeliac and now never eat gluten and I never have problems.
