Why am I suddenly allergic to fast food?

About four months ago I was able to eat Chinese food, Burger King, etc. Now all of a sudden, when I go out to eat I get really really itchy after eating those foods (e.g. french fries; fried chicken; pizza; soda, bagel; coffee, etc.) I also get itchy after chewing gum. I used to be able to chew gum without a problem. Why is this happening. I've also developed swollen lymph nodes all around my neck, groin, inner thighs, etc. I got a biopsy done and I do not have cancer. I got a blood test done and everything came out normal. I haven't had a fever or sore throat, just extreme itch on my body. I went to my allergist and I'm not even allergic to those foods that have been making me itchy...I came out positive only to eggs and hazelnuts, but I haven't even been eating those foods.Why am I suddenly allergic to fast food?
Try another allergist just to be sure, there is something in all these things that you are reacting to. Allergies are no fun, hope that these are short-lived. While the obvious answer is to stop these things that cause the reaction it would still be good for you to know what has been causing this. Just in case.
Meh, call that a blessing :d

Trust me, you'd do better off without eating foods like that.



But.. if you want an absolute answer.. it could be because you've been eating too much of that stuff in the past, so much so that your body can't take it anymore, then it starts rejecting the food completely and developing visable symptoms. I would say that symptoms are the worst stage, when the body can't handle your eating habits by itself, it will force you to take notice of it, a defensive/precautionary action.Why am I suddenly allergic to fast food?
Most fast food would have either an egg component or be prepared on the same cook surface as eggs. Therefore that allergy would come into play.
I ate for free at one of them fast food places haha. You possibly can also, just simply should be quick about it!Why am I suddenly allergic to fast food?
Weird!

Time to see a better allergist.
