In a radiculopathy, the problem occurs at or near the root of the nerve, shortly after its exit from the spinal cord. However, the pain or other symptoms often radiate to the part of the body served by that nerve. For example, a nerve root impingement in the neck can produce pain and weakness in the forearm.
The cervical spinal nerve 6 (C6) is a spinal nerve of the cervical segment. [1]It originates from the spinal column from above the cervical vertebra 6 (C6).. The C6 nerve root shares a common branch from C5, and has a role in innervating many muscles of the rotator cuff and distal arm, [2] including:
So, for example, a right postero-lateral herniation of the disc between vertebrae C5 and C6 will impinge on the right C6 spinal nerve. The rest of the spinal cord, however, is oriented differently, so a symptomatic postero-lateral herniation between two vertebrae will impinge on the nerve exiting at the next intervertebral level down.

If neck pain is the result of instability, cancer, or other disease, surgery may be necessary. Surgery is usually not indicated for "pinched nerves" or herniated discs unless there is spinal cord compression or pain and disability have been protracted for many months and refractory to conservative treatment such as physical therapy.
Nerve compression syndrome, or compression neuropathy, or nerve entrapment syndrome, is a medical condition caused by chronic, direct pressure on a peripheral nerve. [1] It is known colloquially as a trapped nerve, though this may also refer to nerve root compression (by a herniated disc, for example).
A dad, 45, had what seemed like a pinched nerve. It was a sign of a cancerous thymoma. Chest pain, shortness of breath were signs of his thymoma.
Numbness Numbness occurs when one develops a "pinched" nerve not allowing for the flow of electrical charges, which may result in the death of the nerve fiber. [3] Weakness An individual becomes weak due to the compression of nerves encompassing cervical spine disorders, thus resulting in the inability to move or use arms. [3]
Cervical spinal nerve C7 controls triceps and wrist extension. Cervical spinal nerve C8 helps control the hand. [18] The cervicocranial syndrome occurs when symptoms arise due to cervical vertebrae damage (misalignment, collapse, shift or disease, such as tumor) resulting in the improper functioning of the cervical spinal nerves.
