Pret allergy?

[Newbielondon]

Hi everyone - I had a breakfast roll, mocha coffee and pain aux raisin from Pret, Heathrow whilst on board a BA flight travelling to Greece.

Immediately after I had the roll which was their egg bacon and sausage - I felt a tingling in my lips, then one side of my face was starting to feel numb as well and before i knew it i couldn't feel one side - that's when I started to panic as I thought I was having a stroke! The cabin crew were amazing - sprung into action gave me oxygen, water had me sit in the cabin crew seats so i have more space. They called Dr on board, notified pilot and also called Dr in America. However nobody could conclude what it was.... I then had episodes of vomiting which took everything I just ate out and I immediately started to get the feeling back in my lips and face. I checked the ingredients on the website and I've eaten everything listed before so I don't know what could have caused this reaction...

Has anyone had this before or can comment?

Pret just said sorry and gave me a gift card for £20 - but they couldn't give any further information. Hmmmm
