Two days ago I noticed that when ever I look up and to the left my left eye would get this stabbing like pain that felt like it came from behind my eyeball. Later that night when looking in the mirror I noticed my left eyelid was getting red and puffy. Its two days later and my eyelid is now very swollen and if it gets any more swollen I will not be able to open my eye. I now also have a headache to go with it but I haven't detected a fever.
I wear contacts but have not worn them in almost a week, instead I wear my glasses. I have had surgery on my left sinus passage which damaged the tear duct in my left eye.
What should I do? I'm really starting to get worried now.
