Maybe 3 years ago, I had an eye injury.. but I've never been to the hospital. Every now and then I'll wake up and my eye is constantly hurting, running, and all the above. I'm afraid to go to the doctor, but the symptoms have gotten worser. Do anyone have any clue to what's going on with my vision?

You don't sound logical. If it is your vision you are worried about then why wouldn't you go immediately to have it checked out. Do you want to be blind, vision impaired or whatever. How do you think we could possibly diagnose your ailment based on what you say ?

I work in health care and more specifically I work in the eye care field. I'm an Optician but not yet an Optimetrist! I would suggest making an appointment with your Ophthalmologist. You can run away from problems.
