Neck pain is very common. Usual treatments include drugs (painkillers, anti-inflammatory drugs, and muscle relaxants) and, once the pain is less acute, exercising the neck and learning ways to prevent injuries that cause pain. Because medicines do not always work, some people use alternative treatments, such as spinal manipulation. This treatment consists of physical maneuvers to adjust and mobilize bones in the neck and back. It is used by chiropractors, physical therapists, and osteopaths. Spinal manipulation relieves pain in many persons, and it has been shown to help with acute lower back pain. However, it has not been compared with medicine or exercise as a treatment for neck pain.
