Wow-- I'm sorry that you're going through such a rocky spot in figuring out successful avoidance.
I know that a lot of us have been where you are, though. It
does get better, but I will also say that until you DO know what you're actually allergic to, chances are pretty good that you're going to continue reacting to... well, to a lot of things that probably WON'T bother you once you get everything turned right side up again.
That's the good news!
The bad news is the reality that you're living with right now-- food is the enemy, basically, and you probably have NO idea what is going to happen anytime you put something in your mouth, huh? It's an awful feeling, isn't it??
A suggestion to get you through the next few weeks?
Consider ALL food but {basic staples that you've prepared yourself} to be off limits. No matter what.
FRESH, whole fruits (other than those you know you need to avoid), rice, potatoes, plain protein sources (chicken, pork, etc.). Stay away from restaurant food, prepared foods of ANY kind, and pretty much anything that comes from a box or can. I know that is
really hard. But feeling okay is completely worth it. Trust me. If you have developed an allergy to a common seed (like sesame or sunflower, both increasingly common allergies), food labels won't always tell you what you need to know to eat safely. Think of your body's immune system and allergic response as being like a cup that can only hold so much before it overflows (and produces reactions). As long as you keep having moderate-to-major reactions, you're basically pouring more stuff into a cup that needs to have time to evaporate and get empty... and then ANY little thing is going to be enough to push it into overflow mode. That's why you might eventually find out that you are only really "allergic-allergic" to three or four foods-- but right now, you need to give your body time to calm down some and get that cup empty so that you and the doc can figure it out!
A word about benadryl and food allergies.
BENADRYL WILL NOT STOP YOU FROM DYING OF ANAPHYLAXIS. Seriously. Sorry to alarm you-- but PLEASE check out the anaphylaxis grading chart on the main board, print a copy, and keep it with you as a reminder why you have to just say "no, thanks" to food you don't know pretty much everything about. I'm very concerned for your safety.
I'm really glad you found us, too. Hopefully life will get better-- and easier, too-- with time and once you and your doctor can figure out what is at the bottom of your new reactivity.
