Neck pain is discomfort in any of the structures in the neck. These include muscles and nerves as well as spinal vertebrae and the cushioning disks in between. Neck pain may also come from areas near the neck such as the shoulder, jaw, head, and upper arms.
When you have neck pain, you may have difficulty moving it, especially to one side. Many people describe this as having a stiff neck.
If neck pain involves nerves (for example, significant muscle spasm pinching on a nerve or a slipped disk pressing on a nerve), you may feel numbness, tingling, or weakness in your arm, hand, or elsewhere.
