Around Dec. 1 I had a sudden onset of skin itching and burning about 2 hrs. after a meal. I also felt queasy and feverish. The itching and burning have continued (usually ears, scalp, backs of hands), along with a facial rash. Symptoms subside slowly and then recur after next meal. Sometimes I feel uncomfortably warm and the palms of my hands get bright red. No recent changes in diet, cosmetics or detergents. Family dr. ran bloodwork which was normal. I can also experience the symptoms early in the morning before I've eaten anything. I've tried eliminating various foods and reintroducing them; haven't been able to identify many patterns, though I did react badly to beef and have been avoiding it. I've also started experiencing a sense of tightness and pressure near my lower right ribs; this usually happens when I'm lying down, doesn't happen every day, and there's no outright pain. I have Sjogren's syndrome and other family members also have autoimmune disorders, so this kind of thing makes me nervous, as well as uncomfortable. Should I see a gastroenterologist?
