I had my J-pouch take down in 1991. Everything has been mostly fine since. About 5 years ago I started getting very itchy areas on random parts of my body. These can appear just about anywhere. There is not much rash - just a small raised spot (like a small pimple). The allergist found nothing and my dermatologist is going nuts trying to figure out what this can be. He sent me for a very extensive blood test and CT scan. Neither turned up anything. He believes this is autoimmune in nature - responds to steroidal creams and Prednisone.
I was wondering if anyone else has encountered anything like this and received a diagnosis?
