I have had neck and vision problems for over 30 years. Primarily the muscles on the left side of my neck are chronically tight. This affects my vision considerably. I have found that at the top of the left side of my neck, at the base of my skull there seems to muscle that is spasmed or locked up. There is constant pressure on my eyes, making it very difficult to read. I have been to doctors, chiropractors and massage therapist and none of them have provided any relief. The only thing that has given me any relief is certain stretches that I can do, then my vision is improved and I can read and retain what I've read somewhat better. If I stretch the upper left side of my neck I experience the most benefit. However, the relief is only temporary ( an hour or so) and my neck tightens up again and there goes my vision.
I would appreciate any imput that you may have.
