I woke up 2am last night feeling sick & ran to bathroom. a little bit of diarrhea.. thought I was going to throw up... My hands & feet starting burning, then itching. Next thing I knew I had welts all over... legs, back, stomach & even a little on face. A little bit of breathing issue, but not much.... itching terrible lasted 1 1/2 hrs. I took Benadryl as soon as the itching started. Had some peanut butter about 5-6 hours earlier... suppose to be slightly allergic to peanuts, but never had a reaction before... testing done years ago...
