Question
I'm still confused.  I have had neck pain and burning sensation since Jan.05 and torn tendon in the right arm.  I agreed to surgery after a couple of months of OT. According to the surgeon, I understand that I need to find ways to adjust to my deficiencies to allieviate the arm pain.  Even though I have had additional PT and epidural injections are you stating that my headaches and neck pain/burning are only due to my body posture and movment?   
-------------------------
Followup To Question - Impression:
1.There is a moderate, predominatntly central disc-type defect at C3-4, which approaches the ventral cord surface.
2.At C4-5, a mild diffuse extradural disc-type defect is noted with bilateral mild to moderate foraminal narrowing.
3. At C6-7, there is a mild left-sided extradural disc-type defect with associated mild foraminal encroachment.
Answer - Dear Connie,
An array of symptoms can come from neck muscles in contracture, headaches being one of them.  Occipital muscles in contraction generate frontal headaches.  Scalenes in contraction impinge on the brachial plexus and lead to symptoms in the upper extremities.  Vertebral/disc compression are common.  The muscles themselves are prone to spasm and soreness.  Tendinitis is not a surprising aftereffect to surgery, as the systemic response to injury surgical is to shorten muscles and retract the involved area.  Chronic heightened muscular tension stretches and irritates tendons.
In short, it sounds to me like you are experiencing somatic reactions to injury, reactions that cannot be ameliorated by surgery, drugs, or manipulation, but only by sensory-motor training.  You need to improve your control of the involved muscles, to the degree of relaxation.  You can justifiably expect rapid symptomatic relief and functional improvements.
Rather than take extra space, here, I refer you to articles at somatics.com/page4.htm.  The titles are self-explanatory and the articles, concise.  with regard, Lawrence Gold

Answer
In a word, yes -- but that's a bit of an oversimplification.

Body posture and movement reflect muscular function, controlled by brain-level sensory-motor learning.  Headaches are a reflexive result to contracted cervical muscles (retraction of the neck and head).  Muscles in contraction fatigue and burn, accounting for neck pain.

Narrowed foramina do not always cause symptoms.  Nerve impingements and muscular contractures always do, to one degree or another.
