A bony growth that forms along the edge of a bone.

Bone spurs often form where bones meet each other — in the joints. They also can form on the bones of the spine. The main cause of bone spurs is joint damage linked with the most common type of arthritis, called osteoarthritis.

Often, bone spurs don't cause symptoms. But sometimes, they cause pain and loss of motion in joints. The exact symptoms depend on where in the body the bone spurs are located.

If bone spurs cause symptoms, pain relievers sold over the counter may help. So might physical therapy. Surgery for painful bone spurs due to arthritis may be recommended if other treatments don't work.
