A heel spur is caused by the displacement of calcium on the bone that forms on the underside of the heel, it may be one small bony protrusion or a collection of tiny, irregularly shaped growths on the bone of the heel, which is called the calcaneum. Heel spurs are sometimes painful, described as a knife digging into the heel and other times, a heel spur goes unnoticed and is only detected by an X-ray.
One common cause of heel spurs and related injuries is due to abnormal mechanics and movement of the foot, also referred to as pronation. Abnormal gait, which is the way our feet hit the ground as we walk, also stresses the tissue of the foot, leading to conditions such as plantar fasciitis and heel spurs. Pronation can cause the foot to become unstable during movement, affecting the gait and leading to damage. A sudden increase in weight can also influence the development of a painful heel spur.
An individual with the lower legs turning inward, a condition called genu valgus or "knock knees," can have a tendency toward excessive pronation. This can lead to a fallen arch and problems with the plantar fascia and heel spurs. Women tend to suffer from this condition more than men. Heel spurs can also result from an abnormally high arch. Other factors leading to heel spurs include a sudden increase in daily activities, an increase in weight, or a thinner cushion on the bottom of the heel due to old age. A significant increase in training intensity or duration may cause inflammation of the plantar fascia. High-heeled shoes, improperly fitted shoes, and shoes that are too flexible in the middle of the arch or bend before the toe joints will cause problems with the plantar fascia and possibly lead to heel spurs.
A thorough medical history and physical exam by a physician is always necessary for the proper diagnosis of heel spurs and other foot conditions. X rays of the heel area are helpful, as excess bone production will be visible.
Non Surgical Treatment
Exercise. If you think your pain is exercise-related, change your exercise routine, environment, or foot-ware, and emphasize movements and/or body parts that do not cause pain. Mind/Body. Occasionally foot pain can be related to stress. The body may respond with generalized tension that contributes to pain in many areas, including the feet. Hypnosis and guided imagery are worth exploring if an anatomical problem is not apparent. Supplements. Natural anti-inflammatories can be just as effective as ibuprofen or other over-the-counter pain relievers with fewer side effects. Try one of the following. Ginger (Zingiber officinale) standardized to 5-6% gingerols and 6% shogoals, take one to two 500 mg tablets three to four times daily. Turmeric (Curcuma longa) standardized to 95% curcuminoids, take 400-600 mg three times daily. Also, be sure that you're wearing well-fitting shoes, the proper shoes for each activity, and that you buy new foot-ware as soon as you notice signs of wear. You can also take the pressure off your heel with a donut-shaped heel cushion or a heel-raising pad placed in your shoe. Acupuncture can also relieve the pain, as can for some sufferers, magnetic shoe inserts, although the evidence behind their effectiveness is not conclusive. Osteopathic or chiropractic manipulation can help with soft tissue pain in and around the feet.
Sometimes bone spurs can be surgically removed or an operation to loosen the fascia, called a plantar fascia release can be performed. This surgery is about 80 percent effective in the small group of individuals who do not have relief with conservative treatment, but symptoms may return if preventative measures (wearing proper footwear, shoe inserts, stretching, etc) are not maintained.
