Neck and shoulder pain. Computer X-ray artwork of the back view of a human skeleton's shoulders, neck and skull. The red area represents neck pain (cervicalgia) and shoulder pain. Neck pain, although felt in the neck, can be caused by other spinal issues such as muscular tightness or joint disruption in both the neck and upper back. The shoulder is an unstable joint because of the range of motion necessary. It is easily injured because the ball of the upper arm is larger than the shoulder socket that holds it. Some shoulder problems arise from disruption of the muscles, tendons, and ligaments holding the upper arm in place.
