Approximately 10 per cent of the population may have heel spurs without any heel pain. Whilst recent research has raised the question of whether or not heel spurs are the result of the body trying to increase its base of support, heel spurs are still considered to be the result from strain on the muscles of the foot (in particular the plantar fascia). This may result from a biomechanical imbalance, such as over pronation.
Heel spurs can form as a result of repeated strain placed on foot muscles and ligaments as well as from abnormally stretching the band of tissue connecting the heel and ball of the foot. Repeated injury to the membrane that lines the heel bone can also cause problems as can repeated tight pressure on the back of the heel. The causes can range from excessive walking (especially if unaccustomed to walking), running or jumping to improperly fitted or worn-out shoes. Runners, volleyball players, and tennis players, people who do step aerobics or stair climbing for exercise, those with flat feet, pregnant women, the obese and diabetics and those who wear tight-fitting shoes with a high heel are all prone to developing spurs (and plantar fasciitis) more readily.
Heel spurs often cause no symptoms. But heel spurs can be associated with intermittent or chronic pain, especially while walking, jogging, or running, if inflammation develops at the point of the spur formation. In general, the cause of the pain is not the heel spur itself but the soft-tissue injury associated with it. Many people describe the pain of heel spurs and plantar fasciitis as a knife or pin sticking into the bottom of their feet when they first stand up in the morning, a pain that later turns into a dull ache. They often complain that the sharp pain returns after they stand up after sitting for a prolonged period of time.
Because the diagnosis of heel spurs can be confused with tarsal tunnel syndrome (as described earlier), most surgeons advocate performing a tarsal tunnel release (or at least a partial tarsal tunnel release) along with the plantar fascia release. This surgery is about 80percent successful in relieving pain in the small group of patients who do not improve with conservative treatments.
Non Surgical Treatment
Heel pain may be associated with a heel spur, however the heel pain is usually due to plantar fasciitis, rather than a heel spur, so treatment is usually directed at the plantar fasciitis itself. Treatment usually involves application of ice to reduce pain and inflammation, special stretching exercises, and pain-relieving or anti-inflammatory medicines. Night splints or orthotics may be recommended. It may help to avoid the activities that aggravate pain, such as long walks and running. Surgery is very rarely recommended and only after other measures fail.
Surgery, which is a more radical treatment, can be a permanent correction to remove the spur itself. If your doctor believes that surgery is indicated, he will recommend an operation - but only after establishing that less drastic methods of treatment are not successful.
