The Neck supports and assists in movement of the head. It is the most flexible part of the spine and consists of 7 cervical vertebrae, cervical segment of the spinal cord, spinal nerves, ligaments, tendons and muscles. Neck pain can be secondary to a problem affecting any of these structures.
Usually neck pain occurs due to damage to the soft tissue such as muscles, ligaments and nerves which may occur either due to an injury or wear and tear associated with the ageing process. The cervical spine is more prone to injury as it has comparatively less protection when compared to the thoracic and lumbar spine. Some of the common causes of neck pain include incorrect body posture, disease affecting the spine, trauma, inherited abnormalities of the cervical spine, infection or tumor of the spine. Spondylosis and cervical spinal stenosis may also result in neck pain.
Spondylosis is a result of degeneration of the intervertebral discs between the cervical vertebrae. This increased wear and tear of the vertebral joints cause damage to the cartilage and formation of bone spurs. The intervertebral disc may also protrude out of its normal anatomical space and cause spinal nerve compression.
Cervical spinal stenosis refers to the narrowing of the spinal canal in the neck. It occurs due to age related changes of the spine and its surrounding structures such as thickening of ligaments, degeneration of intervertebral discs and excessive bone formation around the intervertebral joints. A compression of cervical spinal nerves or the spinal cord, due to any of these factors, results in neck pain.
The intensity of neck pain may be vary from mild to intense and may be associated with difficulty in movement of the neck (neck stiffness). The affected region may be tender to touch. Neck pain may also be associated with numbness, tingling or weakness in the arm or hand. Neck pain may sometimes also lead to gait and balance disturbances, headache, dizziness, jaw pain and ringing in the ears. In rare cases neck pain may also be associated with loss of bowel and bladder function.
Proper diagnosis is crucial for effective management of neck pain. To arrive at an accurate diagnosis, a detailed medical history coupled with a physical and neurological examination is essential. Neurological examination helps identify any signs of neurological injury and involves evaluation of reflexes and muscle weakness. An X-ray or CT scan of the neck may also be required to confirm the diagnosis.
Non-surgical options for the management of neck pain include activity modification, pain medication, non-steroidal anti-inflammatory drugs, muscle relaxants, physical therapy and spinal injections. A neck collar may be recommended for few days to keep the neck still and reduce mechanical pain due to movement.
Surgery is rarely required for treating neck pain. Surgery is considered only if pain and symptoms fail to improve with non-surgical treatment and neurologic dysfunction and neck instability are evident at diagnosis.
