I have an allergy to bacon. When I eat bacon or country ham I get flushed real red skin nausea, lips get numb, extreme pain in my gut, I through up , and diarrhea. My temp drops to 94 , bp goes down. I have passed out. Is there a test that can be done to see if the Nitrates or Nitrites in bacon or other meats causes this. My doctor has prescribed an epi pen.
