Hi. I just got out of the shower, and my eye started itching, so I rubbed it thinking it wasn't a big deal. Then I rubbed some more, and looked in the mirror and noticed my upper eyelid had started to swell next to my eyelashes. It still itches a bit, but I just rinsed it with cold water and now it's not as itchy. It is however, getting more swollen by the minute. I'm not allergic to anything, so I don't know what's going on...
