all of your symptoms can be explained by the MRI (I assume it was of your neck). However, to be sure you should get checked anyway....the neck pain/spasms can go along with the buging dics which push on nerves and cause pain...the headache can also be explained because the muscle around the head are controlled by those nerves too...the only thing that is a little off is the blurry vision...i would recommend getting a brain CAT scan or MRI and having blood work and your vision checked....be sure, get checked...
GOOD LUCK AND I HOPE YOU FEEL BETTER!
