Bone Spurs on Heel
By Theresa Adams ATC
Bones Spurs on the Heel can be very Painful
A heel spur is a calcium deposit causing a bony protrusion on the underside of the heel bone, a process that usually occurs over a period of many months. Heel spurs are often caused by strains on foot muscles and ligaments, stretching of the plantar fascia, and repeated tearing of the membrane that covers the heel bone. Heel spurs are especially common among athletes whose activities include large amounts of running and jumping. 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.
Although many people with plantar fasciitis have heel spurs, spurs are not the cause of plantar fasciitis pain. One out of 10 people has heel spurs, but only 1 out of 20 people (5%) with heel spurs has foot pain. Because the spur is not the cause of plantar fasciitis, the pain can be treated without removing the spur. Your doctor may order imaging tests to help make sure your heel pain is caused by plantar fasciitis and not another problem. X-rays provide clear images of bones, and heel spurs can often be seen on an x-ray. They are also useful in ruling out other causes of heel pain, such as fractures or arthritis.
