Hello. I'm new to this site. I probably should start off with a few things about myself to help you guys help me. I've been bruising easily since 6 or so. The rashes started up at age 19. I'm 21 now. I was diagnosed with cat and dog allergies. I'm also allergic to soy and water chestnuts. I had my gallbladder removed in 2014. Age 18. Really the only thing that's a problem is the rashes/hives. I have pictures. And please don't suggest cancer, I've already been checked for all common causes. The doctors have been stumped by me since 6.
