What are the symptoms?
Many people have bone spurs without ever knowing it, because most bone spurs cause no symptoms. But if the bone spurs are pressing on other bones or tissues or are causing a muscle or tendon to rub, they can break that tissue down over time, causing swelling, pain, and tearing. Bone spurs in the foot can also cause corns and calluses when tissue builds up to provide added padding over the bone spur.
How are bone spurs diagnosed?
A bone spur is usually visible on an X-ray. But since most bone spurs do not cause problems, it would be unusual to take an X-ray just to see whether you have a bone spur. If you had an X-ray to evaluate one of the problems associated with bone spurs, such as arthritis, bone spurs would be visible on that X-ray.
How are they treated?
Bone spurs do not require treatment unless they are causing pain or damaging other tissues. When needed, treatment may be directed at the causes, the symptoms, or the bone spurs themselves.
Treatment directed at the cause of bone spurs may include weight loss to take some pressure off the joints (especially when osteoarthritis or plantar fasciitis is the cause) and stretching the affected area, such as the heel cord and bottom of the foot. Seeing a physical therapist for ultrasound or deep tissue massage may be helpful for plantar fasciitis or shoulder pain.
Treatment directed at symptoms could include rest, ice, stretching, and nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen. Education in how to protect your joints is helpful if you have osteoarthritis. If a bone spur is in your foot, changing footwear or adding padding or a shoe insert such as a heel cup or orthotic may help. If the bone spur is causing corns or calluses, padding the area or wearing different shoes can help. A podiatrist (foot doctor) may be consulted if corns and calluses become a bigger problem. If the bone spur continues to cause symptoms, your doctor may suggest a corticosteroid injection at the painful area to reduce pain and inflammation of the soft tissues next to the bone spur.
Sometimes the bone spurs themselves are treated. Bone spurs can be surgically removed or treated as part of a surgery to repair or replace a joint when osteoarthritis has caused considerable damage and deformity. Examples might include repair of a bunion or heel spur in the foot or removal of small spurs underneath the point of the shoulder.
