A heel spur is a bony fragment that points out from the heel bone and goes into the sensitive tissues and nerves causing foot pain with each step. Foot pain is usually associated with activity, but can be quite pronounced in the morning.
When the plantar fascia is excessively and repeatedly pulled from the heel bone, the pointed growths of bone develop. Abnormal gait can also be a factor in the development of heel spurs. The stress of having the foot repeatedly hitting the ground in unusual ways promotes the development of calcium where the plantar fascia attaches to the heel bone. This causes the heel spur.
As with most foot pain, heel spurs can be treated with methods such as anti-inflammatory medications, cortisone injections, and of course, icing. If these methods do not work, surgery can be considered.
