I have had pink eye once in my life ( I think ) when I was about 13.
I had stayed home because of a bad allergy attack. My right eye was very itchy, and I kept itching at it and picking goop out of it. My eye would water, but it would not be tears.
I decided to look in the mirror, and to my horror, my bottom eyelid was puffed up to the point were I could not close my eye anymore! I pulled the lid down a bit and saw that the tissue there was swollen and filled with pus.
It freaked me out, but quickly went away in about an hour...
It sounds like pinkeye, but nobody else in my family got it, and I never went to the doctor. Might have been an allergic reaction to something, like a pollen or dander.
I hope you feel better soon. It may be icky, but consider yourself lucky! I have had a bad intestinal bug for about 3 days, now I am starting to recover and can finally start to eat normally/not get horrible cramps/not have to poo every hour...
