I am allergic to pet dander, I got horses hair in my eye and about an hour later I was itching and then my right eye swollen shut and I put in visine eye drops and my eye started forming lumps everywhere underneath the eyelid with a thick yellowish fluid. My throat started itching and I could not breat that well, I took benadryl and Loratine. It has been 10 hours and my eye is still swollen and I can not see out of it and under my eye and cheek is very swollen still.
