Even though you say you don't think it's a stye, that is what it sounds like. Or maybe even a cyst. I had a cyst on my right eye that was painful and made my eye swollen, eventually I had to have it surgically removed. My eyelid would swell up so large that it took 2 hours of warm compresses to take down the swelling. Definately go and have this checked out by a doctor. In the meantime, try using warm compresses every 20 minutes for about 5 minutes each time. I would take a washcloth, put it in a plastic baggie and microwave it to heat it - warm not hot. They also have a stye cream you can use from the pharmacy. Even if you don't have a stye, it might help alleviate some of the irritation. Or I just thought of another possibility, maybe even a blocked tear duct. In either case, the warm compresses should help a lot. And btw, welcome to Healingwell.
