Any doctors out there?

Perhaps you are allergic to mushrooms or any of the gunk in cream soup (one of the worst "foods" out there). You'll just have to experiment with foods to see which ones set you off or not.

Not a doctor myself, but sounds like a food allergy. Can you eat mushrooms in other foods? If so, the problem might be with a different ingredient in cream of mushroom soup. I suggest checking the can's list of ingredients and taking note of which ones you know you've eaten before; then, by process of elimination, see which of the remaining ingredients might be listed in other foods which make you ill. Might be some lesser obvious ingredient like monosodium glutinaite (msg). Best wishes to finding what's wrong. ;)
