You think that was sarcasm? Heh. It was a question about detail you omitted. You gave minute detail about everything, including your pubic hairs (<<===that was sarcasm), and didn't say a thing about what you were told at the hospital.
Why should I play a guessing game of what could have been the cause when you already had the brain trust of a hospital emergency room working on the issue for you and didn't bother to give us that information.
I had dinner at my uncles he made home made raviolis and other Italian foods that I have never tried
You want some better answers? Ask your uncle to detail all the ingredients, herbs and spices in the food he prepared for you. Then, either look up the foods yourself to see if there is a history of allergic reactions to any of them or come back here and post a useful list of them and we will help you Google the history of allergic reactions.
Do you have a history of allergies to any insect bites or seafood? That would be good info to have too.
