Joint Pain OverviewJoint pain can be caused by injury or disease of the joint or adjacent tissues. A joint is the area at which two bone ends meet to provide motion to a body part. A typical joint is composed of bones that are separated by cartilage that serves as cushioning pad for the adjacent bones. Ligaments attach bone to bone around the joint. Bursae are fluid-filled sacs that provide a gliding surface for adjacent tendons. Tendons attach muscle to bone around the joint. Injury or disease to any of the structures of the joint can lead to pain in the joint. Joint pain is also referred to as arthralgia. |

Ankylosing spondylitis can also affect other joints away from the spine as well as cause inflammation of tendons and ligaments.
