- Joint 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.
