What is A Heel Spur?
A heel spur is a calcium deposit causing a bony protrusion on the underside of the heel bone. On an X-ray, a heel spur can extend forward by as much as a half-inch. Without visible X-ray evidence, the condition is sometimes known as “heel spur syndrome.”
What Are The Symptoms?
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.
What Causes A Heel Spur?
Heel spurs occur when calcium deposits build up 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.
Risk factors for heel spurs include:
- Walking gait abnormalities, which place excessive stress on the heel bone, ligaments, and nerves near the heel
- Running or jogging, especially on hard surfaces
- Poorly fitted or badly worn shoes, especially those lacking appropriate arch support
- Excess weight and obesity
What Are The Treatments?
The heel pain associated with heel spurs and plantar fasciitis may not respond well to rest. If you walk after a night’s sleep, the pain may feel worse as the plantar fascia suddenly elongates, which stretches and pulls on the heel. The pain often decreases the more you walk. But you may feel a recurrence of pain after either prolonged rest or extensive walking.
If you have heel pain that persists for more than one month, consult a healthcare provider. He or she may recommend conservative treatments such as:
- Shoe recommendations
- Taping or strapping to rest stressed muscles and tendons
- Shoe inserts or orthotic devices
- Physical therapy
- Night splints
Heel pain may respond to treatment with over-the-counter medications such as acetaminophen, ibuprofen, or naproxen. In many cases, a functional orthotic device can correct the causes of heel and arch pain such as biomechanical imbalances. In some cases, injection with a corticosteroid may be done to relieve inflammation in the area.
Surgery for Heel Spurs
More than 90% of people heal with nonsurgical treatments. If conservative treatment fails to treat symptoms of heel spurs after a period of 9 to 12 months, surgery may be necessary to relieve pain and restore mobility. Surgical techniques include: release of plantar fascia and/or removal of the spur.
