There are multiple factors that can cause neck pain and neck tension: a common cause of a stiff neck is a twisting or whiplash injury from jerking the neck too hard, for instance in a car accident or a sports injury. A stiff neck or neck tension can also occur after sleeping with the neck in an awkward position. Another cause may be a spasm of the neck muscles or a fibrotic inflammation. Osteoarthritis and osteoporosis as well as degenerative disks or misaligned vertebrae in the cervical spine can also cause discomfort in the neck.
If stiffness is caused by an injury, then heat, traction or massage may be required. Pain killing drugs and anti-rheumatic drugs (in case of swellings) may be prescribed.
Receiving remedial massage therapy for release of tension and stress and increased circulation and Qi flow, checking for leg-length difference, correction of any misalignment of the pelvis and the spinal vertebrae can address adverse symptoms and their causes on multiple levels of the functions of the human body systems.
