It's only been like that for the last few years, not all my life.
Whenever I eat hazel nuts, right after that I'm fine and I can eat them forever, but after I've slept for a bit or next morning my mouth is swollen and I'm drooling really badly. My tongue is swollen and stiff and I can't taste anything, my lips have big watery blisters on the inside, the throat is swollen aswell I think cause when I breathe I breathe with snorts and I drool a lot.

I think it's only hazel nuts. I had it really bad when I ate a packet of them, so I thought I just might have over done. But the next time I had a chocolate that had hazel nuts in it. I had about 2 or 3 nuts, a few bites and I had the same thing in the morning.

I'm just confused, cause I've had food allergy tests done, blood test and the special machine test and nuts didn't show up there. And I never had anything like it when I was a child.

My health has changed over the last few years though, could it be because of that?
