My left shoulder has hurt since Feb when I had a regulator placed (for DBS) on the right side. I figured over use since right side was healing. Also I have had a cervical fusion C3-7 2.5 years ago. I am now having pain in C2 area, down neck, across the back side to my shoulder, and pain is now radiating past elbow. Limited movement, loosing ability to open bottles. The area is acting both neuro and bursitis or tendinitis. Any ideas? Tylenol, Motrin, soma and Norco s have no effect, also Lyrica. Getting worse daily. Help or ideas?
