Jayne, you have spinal stenosis in your cervical spine. Because there is insufficent space to pass through, your nerve root is pinched. I have the same problem. I also have had four lumbar spine surgeries, including multilevel fusion. All four of my spine surgeries failed.
Surgery should always be a last resort, after failure with PT and pain management. You can also try traction. If all of these fail to help and you remain miserable, you can consider fusion.
However, there are some things you should know first:
1. Spine surgery is 80% successful for improved function (less arm or leg radiculopathy), but only 50% successful for pain. Yet, most people have the surgery for pain. So, surgery is just as likely to fail as to succeed.
2. For cervical surgery, you can have disc replacement, which is much better than a standard fusion. It offers the mobility of a discectomy with the stability of fusion. Disc replacement is stil considered experimental for lumbar surgery, where body mass is many times greater than cervical vertebra hold. But, I would not (will not) have cervial surgery without disc replacement.
3. You should only trust your spine to a spine surgeon. A spine surgeon is someone who has completed a fellowship in spine surgery (about 3-4 years AFTER a residency) and who restricts their entire practice to trauma and disease of the spine. No orthopedic surgeon or neurosurgeon can come close to a spine surgeon for experience, training and technique. Spine surgeons are at the leading edge of their field. They were the first to use disc replacement, rods, pins, cages, etc., and they are light years ahead of standard surgeons for technique. Spine surgeons can typically be found at or near teaching hospitals (universities).
Whatever you decide to do, good luck.
