You need to have more than an eye doc look at you. You could have anything from migraines, to cluster headaches to a tumor or just stress headaches...or who knows what. Please get to your regular doctor and have him refer you to a specialist he thinks is best.
Keep in touch,
I agree with Chutzie. I think you should look into getting a MRI done of your head, to rule out tumors, they could be what is putting pressure or pain on your eyes. You just never know....better safe than sorry!
