Iam having allergy for the last 2 mnths no medicine can help,my face gets swollen,no itching.?

if i dine out mostly chinese,then this problem crops up,with homeopathy it was a bit in decline but suddenly that also is not working now.no pain or itch is there but one side of the face gets disfigured,swollen.am a vegetarian,no fish or eggs is been taken,once in a while i take beer.doctor saying pesticide,carbide in fruits,vegs is the culprit.i want to know the exact cause and remedy for it.

I also have terrible food allergies too, usually it is the seasoning in food like the MSG that they use, or nuts or the food is not cooked properley, I usually itch and have swelling really bad all over my body, The doctor prescribed a tablet for me named Aerius, that is what i have to take if an attack occurs.
You can also take any antihistamine medicine, that is the best way to go, but if it is really not working the doc may suggest you take an injection named Epipen, that is usually the last resort for me. Hope the info helps and hope you feel better soon!.
P.S if you do not rinse your veg and fruits you may want to start doing that.

dude, you are going to have to change your diet. You might be suffering from food allergies but a very serious case. This means that you might have to eliminate grainy foods and dairy. but thats ok because you can find subsititutes for them. When you purcahse fruit or veggies do you wash them off?? You might have to buy a wax/ pesticide removal spray to eliminate some of those by products from your food. If you feel a reaction about to occur take Benadryl and drink plenty of water. Def go to an allergiest, because they will be able to administer tests to you to determine what exactly it is that you are allergic too. good luck.
Did your doctor suggest MSG? It is commonly found in chinese takeout, and I know a couple of people wo have similar reactions to it.
