What are heel spurs?

A heel spur is a bony growth that forms on normal bone. It can be at the site of pain but typically is not the cause of pain. The cause of the pain is from the plantar fascia that inserts near the heel spur. Usually people with a heel spur complain of a sharp pain in the heel when they get up in the morning.

Heel spurs are abnormal growths of bone or calcium that can resemble a cowboy's spurs. They sometimes form on the back or bottom of the heel bone. The heel spurs themselves don't cause pain, but sometimes the plantar fascia or other tissues around the spur become  degenerative or inflamed and start to hurt.

Physiology
Heel spurs are growths - calcium deposits - that develop on the back of the heel bone or where the tendon that connects the toes to the heel (called the plantar fascia) attaches to the heel bone. It's common in people who have flat feet, but it can also affect people who have very high arches, too. Obese people, runners and joggers are at an increased risk for heel spurs. The condition can be associated with plantar fasciitis, an inflammation of the tendon on the bottom of the foot.
