Bone spurs, or osteophytes, are smooth, bony growths, usually occurring on the joints throughout the body. The feet are a common area for bone spur development and they often develop gradually over time in patients with arthritis or joint damage. Most bone spurs don't cause problems. But if they rub against other bones or press on nerves, you might experience stiffness and pain.

Signs and Symptoms:
The most common cause of bone spurs is joint damage from osteoarthritis or degenerative joint disease. The cushioning between your joints and the bones of your feet can wear down with age. Disease such as rheumatoid arthritis, lupus, and gout can also further damage joints.
Bone spurs also often form after an injury to a joint or tendon. When your body thinks your bone is damaged, it tries to fix it by adding bone to the injured area. A bone spur can even break off and lodge itself in the lining of the joint. This is called a "loose body" which results in stiffness, and a locked joint.

• Pain near or in the affected joint
• Pain or stiffness when you try to bend or move the affected joint
• Knobs or bumps under your skin
• Weakness, numbness, or tingling
• Muscle spasms, cramps, or weakness

Your symptoms might get worse when you exercise or try to move the affected joint. A healthy lifestyle can delay symptoms like pain, stiffness and limited motion. Medications, physical therapy and surgery may help.
