Hello curemyneck, you have some small bony growths around the two bottom vertebral joints in your neck, they are encroaching on your neural foramen, which are grooves that your nerves coarse out of, that are at the side, and toward the rear of your vertebra. See if you can find a picture of a spine with the features on the vertebra labelled.
As far as exercise or adjusting goes ask a good qualified medical practitioner.
