Hi Jax....I had acdf (neck fusion) surgery in 2010 had horrible neck pain one of the major symptoms of neck problems it travel down arms and you get numbness in finger tips. When you stated rock in your neck ---do u mean you feel it outside on your skin? If i were in your shoes I would seek a consult with neuro or spinal surgeon. Request a mri of your neck and back ---xray wont show herinations. Even if turns out you may have herniations (most ppl do) unless there pressing spinal cord no surgery would be required. I come from a long line of spine problems in our family. If you have mild or moderate there are several treament options that may help P.T or ESI (epidural steroid injections) but I don'tdo any therapy until they get down to a proper diagnosis. By chance you from Ireland?? You saying your a mum ...is what made me inquire. Let me know if you have any other questions. I wish you the best of luck and hope you find some pain relief soon.
