Alfred,
Yes, you can feel throat pain from cervical spine problems, particularly around C3. I have experienced that when spasms have moved my cervical vertebrae around. I still do get spasms that affect my neck because of also having thoracic outlet syndrome, and that has also caused my jaw to be too tight and unbalanced which has caused facial and jaw pain and ear pain. These are things I have worked on a lot in physical therapy. Typically neck spasms from spine problems tend to straighten the normal (lordotic) curvature of the cervical spine. In my experience, keeping my curve in line keeps me out of pain, so when I do get spasms, I need to work on them to relax the tension and allow my neck to relax. That is where myofascial release really helps me. I do have to work on the tightness from the surgical scar now and then.

As far as pain radiating, that can be complicated as to what are all the reasons for it, and if there is also any compression of a nerve further down the pathway. Generally speaking, compression at a spinal nerve root follows a dermatome map of where that pain is felt on the surface of the body, so it is predictable. Pain generated by spinal cord compression inside the spinal canal could be anywhere and can change because of differing spine positions because the spinal cord has to move inside the spinal canal and that can change where a pain symptom happens or if it happens or not because of what part of the cord is in contact with something. When spinal cord compression has advanced more so that changing position does not reduce pressure on the spinal cord and there is no fluid space around the cord, it is harder to predict how pain will respond to body position or if changing position will help at all. You can have all of these scenarios going on at the same time making it difficult to find the exact cause of pain, but that is the task of neurologists and nerve testing as well as imaging.
