Chinese food scare

My parents have been ultra careful with what I eat since I have such an intense allergy to peanuts and eggs. The allergist has even cautioned against eating at Chinese restaurants due to excessive peanut cross contamination, but we have been eating at many Chinese restaurants without issues. Today's experience however taught my parents a lesson to be more vigilant about which restaurant we patron! When I had some of my favorite foods (dumplings, tofu, green onion pancakes, rice) from a Chinese takeout lunch today, my lips and chin completely swelled up and my hands starting itching! I was screaming hysterically at our friends' house so we left soon after. I immediately fell asleep in the car, but then woke up 10 minutes later vomiting everywhere! Mommy instantly stopped the car to clean up the mess. When we got home, I started breaking out into hives. They weren't too itchy per se but their appearance fascinated me and I kept wanting to touch them. Mommy had to pin me down to squeeze the 5 ml of Benadryl into my mouth; luckily after a few hours I was back to my old self again. Whew, but not before giving everyone a big scare!
