Bone spurs usually form around joints that have arthritis, in the vertebrae of the spine, and on the heel. When they form on the heel, they may form on the back of the heel but usually form on the bottom of the heel. Of course, this is where all of the body weight comes down with each step. Spurs on the bottom of the heel are usually most painful the first few steps out of bed each morning. The pain may lessen somewhat after walking for a few minutes, but may be intense again after sitting for a half hour or so, such as after lunch. The pain usually gets worse throughout the day as you are up on your feet more. Often the pain feels like a nail being driven through the heel into the ankle and leg.
Over-pronation (flat feet) is a common cause of heel spurs, but people with unusually high arches (pes cavus) can also develop heel spurs. Women have a significantly higher incidence of heel spurs due to the types of footwear often worn on a regular basis.
More often than not, heel spurs have no signs or symptoms, and you don?t feel any pain. This is because heel spurs aren?t pointy or sharp pieces of bone, contrary to common belief. Heel spurs don?t cut tissue every time movement occurs; they?re actually deposits of calcium on bone set in place by the body?s normal bone-forming mechanisms. This means they?re smooth and flat, just like all other bones. Because there?s already tissue present at the site of a heel spur, sometimes that area and the surrounding tissue get inflamed, leading to a number of symptoms, such as chronic heel pain that occurs when jogging or walking.
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 involves releasing a part of the plantar fascia from its insertion in the heel bone, as well as removing the spur. Many times during the procedure, pinched nerves (neuromas), adding to the pain, are found and removed. Often, an inflamed sac of fluid call an accessory or adventitious bursa is found under the heel spur, and it is removed as well. Postoperative recovery is usually a slipper cast and minimal weight bearing for a period of 3-4 weeks. On some occasions, a removable short-leg walking boot is used or a below knee cast applied.
