What causes pain in the back of the neck?

Possible causes of neck pain:

1. Physiological factors: Incorrect posture, sleeping in an awkward position, or exposure to cold may cause misalignment of the cervical facet joints, leading to pain.

2. Muscle or soft tissue injuries: Prolonged poor posture, such as looking down at a phone or working at a computer, or sudden neck movements can cause muscle tension, strain, or sprain, resulting in neck pain.

3. Cervical spine disorders: With aging, the cervical intervertebral discs may degenerate, leading to disc herniation, bone spurs, and nerve root compression, which can cause neck pain and even symptoms such as arm numbness and weakness.

4. Inflammatory diseases: Conditions such as cervical arthritis and myofascial inflammation can cause local pain and stiffness due to inflammatory reactions.

5. Neurological diseases: For example, cervical spondylosis or multiple sclerosis; these conditions may affect the spinal cord or nerve roots, causing neck pain.

If the pain persists, it is recommended to seek medical examination and treatment at a hospital immediately.
