<<Disclaimer: Verify this information before applying it to your situation.>> I don't know where to begin, and I apologize for the length - well - I went GF for 6 days, during which my gi pain & diarhea was much better, almost right away. I decided to get the blood test in Maryland - thanks to all who suggested that. Anyway, I began eating wheat again yesterday and I immediately got itchy welts on my thighs, back of my upper right leg, and am starting to get general itchies. I had forgotten abut last year when I had a couple of bad attacks (gut)& had the same kind of rash: intense itching, so bad I had purple bruises to go with the red raised (almost hive looking) areas some an inch long, with a smaller exposed spot in the middle. They later reduced inflammation to look more bumpy but still red - like they do now. Is it possible to have such a drastic and immediate reaction? I attributed last years rash to red bugs or chiggers which who knows? - May be the case now (I am living in a more rural area). Timing is WEIRD though. I also did some research on DH which I hadn't even considered when I joined this list, but I saw where someone had a lesion that left a white spot and didn't tan over for years - well I remembered as a child, having a white spot that I thought was a birthmark that faded a little when tanned but returned for many years until finally it went away (don't remember when). I also used to get a recurrent (seasonally/summer?) giant hive like thing on the inside of my right forearm. Could any of this be related? It doesn't seem to match the standard description, which I know can vary somewhat, but I just seemes weird to me that when I start playing with the diet - all this happens. Thoughts please? Thanks, Angie
