I have never had this itchy blistery rash until my 2 nd pregnancy. The MD called a pregnancy induced rash. I have had problems for years with bloating, urgency and crampy abdomen. now the itching is bad. The blister stop itching feel better after the fluid leaks out but the wounds heal slowly and bleed a lot if I bump them. I have scars on my legs and a few on my arms. My aunt is gluten intollerant. could this be the problem. I also have frequent out breaks of irisititis.
