I got a massive allergic reaction during the weekend after dinner (when I was playing LOTRO; noticed suddenly I had difficult to breath and to see the screen -> eyes, lips, fingers had all swollen and I had urticaria all over my body), and had to get to the hospital. Could barely breath when I got there, but got good care. I am home already, but not that fit yet, my fingers are still like small balloons.
I am allergic to nuts, but the meal I had wasn't supposed to have them. Not quite sure what caused the reaction thus, which makes this slightly more confusing.
