I woke up with a pain in my left eye two years ago and has been a constant pain for 2 years. Ive had a CT, MRI and have been glaucoma tested they were all clear( no sinus problems). Heat helps but only for a couple of minutes also my vision isn't impaired at all. I also have a very small headache on the left side of my forehead but not all the time. This makes it very hard to concentrate on studying and reading. Its so frusting ive actually punched my self in the head sometimes because it never goes away. If you have any suggestions that would be appreciated
