Suggest Treatment For Puffiness And Redness In Eyelids

I noticed a few days ago that the top of my left eyelid had a bump on it, bu thought I might have scratched it or perhaps the 'fake' eyelashes I were might have caused an irratation, but my eyelid began to become puffyer throughout the day. I have also been told that it could have been a bug bite, possibly a spider bite. The next morning when I woke up, I could barely see out of my eye. So I put ice on it .. cold rag, even went to the tea bag and cold spoon trick and it really didn't help the swelling go down that much. Later that night I noticed a bumb on the INSIDE of the top of my eyelid and for whatever reason squeezed it and noticed a creme like color (perhaps puss) coming out. I didn't fool with it anymore due to the pain and extra redness/puffing it was causing. I have yet to take any antihistimines for this (I was told this could also work). This has been going on for almost 3 days and it just doesn't seem to be getting better. WHAT CAN I DO??? PLEAE HELP!!!
