Friend is Alergic to chicken!?

So, she said when she was 12 she passed out from eating KFC, and like, when she ate Mc. Donald's chicken sandwich she was really cold, and shaking. Last night we had BBQ chicken wigs, my dad cooked them. Her and I went to a norther friends house and we just hung out and then she fixed her chicken ramen... and it got worse. She randomly buckled over in the floor in pain. Then we went outside and she was like "Im dizzy... Oh god I cant move" and almost collapsed. I had to carry her inside, then she layed down and the other friends mom brought her benadryl and it gave her really bad dry mouth and dehydration. Shes downed SO much watter. Shes now at my house, and every time you mention the hospital she starts having a panic attack.

Her systems are; Headache, stomach ace(lower stomach), very weak, dry mouth, horse, dizziness, she did vomit a little earlier, ichie back and bellybutton, It looks like she has a little Ezma around her bellybutton, arms and bottom has cold tingles...

Please help...
