If you didn't have any sort of hit or re injury, I'd look into the sore neck and vision symptoms..
If you hit the books /computer a lot for college and had a poor ergonomic set up, it could be a RSI/postural issue.
An experienced PT evaluation, or expert chiropractor (that uses multiple modalities) would be worth a try..
I'm thinking muscle spasms and maybe trigger points from what you describe..
I also had some of those same issues when I was on Lipitor (a statin) for high cholesterol..
