The symptoms of heel spurs are a calcium deposit on the underside of heel bone that causes a bony protrusion and, although heel spurs are often painless, there may be pain under the middle of the heel for a prolonged time, sometimes years. These symptoms may indicate that an original condition of plantar fasciitis has likely become a heel spur.
What causes heel spurs?
Our feet have a thick, fibrous band of tissue called the plantar fascia, which connects our heel bones to the balls of our feet. The plantar fascia stretches and strains when the muscles that form and maintain the arch system of the feet don’t work efficiently.
When this happens, the arches can’t safely manage the vertical forces that are generated by our body weight. As a result, our arches collapse, creating stress and strain on the plantar fascia.
Heel spurs occur when that tissue is continually strained over time and calcium deposits form a bony protrusion on the underside of the heel bone.
