"One of my friends had a frightening experience on Christmas Eve, which we thought may have been caused by 635 in corn chips. She has never had a reaction like it before, but had eaten quite a few corn chips (and not much else) at a family outing...here is part of what she wrote: - there was one bottle of mineral water, one bottle of wine, 2 packets of corn chips and a salad consisting of lettuce, tomato and cucumber!! Not only that but halfway thru the nite I started to get these itching lumps on my neck and legs. Felt ordinary for the rest of the nite and next morning I noticed more lumps and my ears were red hot and swollen. Managed to get thru the day okay but I didn't feel much like eating and was tired. Next morning…I woke absolutely burning and covered in lumps (or hives as you have probably figured out). I tried to get up and shower but I fainted…my lips swelled up and (my husband) was in a panic. The doctor came and gave me an anti-histamine and within an hour I was better but my blood pressure remained low and I had to stay in bed til my body battled whatever I ate that I was allergic to. Today I am better…the hives are beginning to go and no new ones are appearing. I can walk but I have to tell you I am scared. I don't know what I ate…I think maybe the corn chips...they were flavoured." (Melbourne)
