Bless your heart!  That sounds really scary!!!  Peanuts are definately off your diet, to be sure!  The next step might be to try a low histamine diet, which means cutting out all fermented foods.  There is a lot of information on the internet about which foods are low in histamine.  See how you feel when you elimnate all the histamine foods.  Right now I'm in a big flare and all I seem to be able to tolerate are carrots, gluton free bread, and turkey - pretty nutricous huh? LOL.  I ate some blueberries today and I'm itching like crazy.  I won't have to eat like this forever - it will take about 6 months to get my body to calm down and then hopefully I can resume a more normal diet.   Hope this helps - wishing you the best of luck!
