(If you ignore hayfecer and possibly dust)
Today at lunch someone at work kindly bought cookies for everyone, I took one and started eating. My tongue started feeling weird and I asked some people around me is they knew what an allergic reaction felt like. They didn't seem to think that I was having one but it got worse and more symptoms came up. (Tummy ache, throat swelling, head/sinus hurting and itchy mouth and ears)
I stopped eating it and someone went to buy antihistamines with me. Eventually I felt a bit better, I didn't go home straight away because I live alone and don't want to be alone just then. Sat through a meeting about a project I'm starting work on but my tummy was hurting a lot so I went home after that.
On the way home, my skin started itching and I clawed at it. I had a shower to see if that soothed it, when I got out the shower I saw my face was swelling up as well as my groin, underarms, neck, back, shoulders, scalp etc. Off to a pharmacy, they gave me piriton. My skin felt worse, I almost tore my clothes off to get in the shower again. I lay down in bed and tried not to move and eventually I slept.
I woke up a couple times and saw my skin was looking a little better. Now it's really just my eye area that's a bit itchy and puffy.
I think it was hazel nuts that cause the reaction. I never knew I has any allergies before today, so I've always ignored the may contain nuts thing (except for my mum, as she is allergic to Brazil nuts). I'm sure I've had Nutella in the passed because I know I don't like it.
Is it just hazel nuts I need to avoid? Is the next time likely to be worse?
How long does it normal take for the effect to wear off?
TIA
