Okay, so, you do NOT need to go to a crawfish boil.Yes, I do, first and only one was at 47 years old after I made some shrimp scampi for myself. Thought I was just having an regular allergy attack until I started itching everywhere. I drove past 2 ER's not knowing and finally hit a walk in clinic. They were all over me, called an ambulance and the dr jumped into the ambulance and rode with me to the ER. He said that had I not popped a couple of benedryls at the beginning (thought it was the cats fur) that they would have found me on the side of the road into a tree. Sooo....no shrinp, crab, lobster, crayfish or anything else with an exoskeleton. Also have to watch any fried foods in restaurants and like 99% of the Chinese restaurants as they just rinse the woks and don't actually wash them.
