Hi,
About a week ago, my left eye suddenly started burning. I don't know what it was, but my guess is a piece of cat hair or dander, to which I have a minor allergic reaction. The pain subsided, but when I woke up the next morning, the eye was red, the eyelid was heavily swolen, and my eye was itchy. I used antihistamine eye drops, which relieved the symptoms, but they would return after a few hours. After a few days the swelling stopped, but the itchiness kept returning, albeit less frequently. I can deal with the intermittent (though decently intense) itchiness, but I don't know if I should see a doctor about this or if it's in the process of resolving itself.
Before anyone asks, I don't think this is related to seasonal allergies or viral conjunctivitis because it's only the one eye and it had a very sudden onset. I also don't wear contact lenses or wear makeup and I can't think of anything else that could be irritating my eye. I've looked at my eye and I don't see anything obviously wrong in there, but it being my own eye, I could easily miss something.
Thanks
