Morty, a few years back I had this eye infection, in both eyes, and it was really weird - it burned like hell but there was no itching, and no swelling. A little puffiness, but not that horrid swelling. And I couldn't go out without my sunglasses and even that was awful. The doc said I had an eye virus, who knows where it came from, here's some eye drops, no contact lenses or makeup for 3 weeks. The burning went away fairly quickly, and it has never come back. So who knows. Good luck! :)
