Small clustered bumps on forearms, legs, and hands
I am 21 years old and already have about a year and a half with these kind of small clustered bumps on my forearms, and legs. Although I also sometimes get them on my biceps, and on my back although they form like a bigger form of hives and on the back of my legs. I have seen many pictures of dermatitis herpetiforme and they seem very similar, and even match up the characteristics of forming around the elbow in many clustered small bumps. Although I have donde several blood tests and even skin tests and resulted negative for celiac disease or gluten allergic. I have used many cortizone ointments, and injected Diprospan two times in a lapse of a year but they still come back. I have gone to several dermatologists here in Guadalajra, Mexico, where I live, but they simply don't have a straight answer to what is causing this bumps. I have even donde an IgE blood test for sensitivity to foods and suspended the ones I was allergic, but still they keep coming back and causing a lot of itch. I am really desperate and would really appreciate any help. Thank you very much!
