You said you had a cervical MRI, but what about a thoracic MRI -- you'd want it done with and without contrast material -- you'll get better results this way. I agree that an MRI is better than a CT scan as the results are clearer.
If you're not seeing a Neurosurgeon, you might want to get a referral to one, or perhaps an orthopedic surgeon. I prefer Neurosurgeons myself. You could go JUST for an opinion - not necessarily for a surgery consult.
I wish you the best --- I hope you can get some answers. God bless! Hugs, Lee
