A Strange "pain in the neck"

Since I went to the dentist for a cleaning 2 weeks ago, and had to turn my head to the right most of the time, a nerve in the back right side of my neck has been tingling on and off. It mostly happens when I put my head down, or lean forward to look at the computer. I'm unsure what it is. My chiropractor has been working on it this last week, but it's still there. Any ideas?
