<<Disclaimer: Verify this information before applying it to your situation.>> I have a (self-diagnosed intolerance/allergy to wheat and corn). A recent post mentioned duodenitis, which I looked up on the internet but didn't find symptoms, only photos and descriptions. Over the holidays I had a bout of terrible upper chest (under ribs) and back pain, combined with indigestion. Kept me up in the middle of the night for three hours one night (until I upchucked) and an hour or so the next. No nausea but did throw up the first nite after an aspirin, several Tums and some bicarbonate of soda. Had blood test for h. pylori, which was negative. In meantime was put on Prilosec, which seemed to help immensely. Vague pains continue and have sort of settled into my upper left abdomen. I can spend some more money (no insurance) and be checked for gall bladder but am choosing to wait it out, and have stopped taking the Prilosec since I have an aversion to pill-taking and it made me really thirsty. For several weeks before this incident, I had been having extreme chills every afternoon, usually after a meal. No fever. Just chills and cold hands and feet. Only way to get warm was to take a hot shower or go to bed and pile on the comforters for about an hour. My thyroid level tested o.k. Any idea what's going on here? Are these symptoms of: 1. ingesting wheat? (my previous symptoms were itching, anxiety, diahrea). 2. celiac-caused duodenitis? Has anyone else had recurring chills without fever? Anna I also take thyroid replacements and Prempro.
