Recently I suffered an extremely itchy rash that kept me up at night and became very inflamed and sore from scratching.  I consulted the doctor and all he could tell me was that it was a rash, and it could be a virus. That was all he could tell me. That and he asked if I'd ever had chicken pox ... this rash was nothing like a chicken pox rash.  The rash itself lasted two weeks and was agony, to say the least.  I still bear marks on my arms from scratching.  I went through the usual what did you eat routine and nothing out of the ordinary - although I did have Hungry Jack’s in the 30 hour time frame.

(Later) As I tend to avoid most overprocessed foods, I can honestly say that my rash after 3 weeks is much better. The rash I developed was small, intensely itchy bumps over my stomach and back, and my arms.  These bumps were constantly itchy, antihistamines helped but did not alleviate much.  I couldn't sleep and felt irritable – although that had a lot to do with no sleep.  However I still have some marks on my arms where I scratched too hard – reader by email.
