Heel spurs usually form under the base of the foot or the back of the heel bone. Spurs that develop underneath the foot may visibly protrude through the skin. In addition, plantar fasciitis as well as heel spurs may eventually lead to chronic pain that persists for three or more months, especially if the sides and base of the heel bone have been affected. A large heel spur can affect movement and prevent an individual from walking or even standing properly. If a heel spur begins to protrude excessively, then surgery usually becomes necessary.
Heel spurs under the sole of the foot (plantar area) are associated with inflammation of the plantar fascia (fasciitis), the "bowstring-like" tissue stretching underneath the sole that attaches at the heel. Plantar heel spurs cause localized tenderness and pain made worse when stepping down on the heel. Heel spurs and plantar fasciitis can occur alone or be related to underlying diseases that cause arthritis (inflammation of the joints), such as reactive arthritis (formerly called Reiter's disease), ankylosing spondylitis, and diffuse idiopathic skeletal hyperostosis. It is important to note that heel spurs may cause no symptoms at all and may be incidentally discovered during X-ray exams taken for other purposes.
Most of the time heel spurs present as pain in the region surrounding the spur, which typically increases in intensity after prolonged periods of rest. Patients may not be able to bear weight on the afflicted heel comfortably. Running, walking, or lifting heavy weight may exacerbate the issue.
A heel spur is often seen on X-ray as a bony protrusion, which can vary in size. However, because a Heel Spur only indicates increased load on the plantar fascia, and not pain, an ultra sound may be required to assess other actual cause of the heel pain such and may include checking to see if the plantar fascia is inflamed or degenerated.
Non Surgical Treatment
Treatment of heel spurs is the same as treatment of plantar fasciitis. Because these problems are related, the treatment is the same. The first step in the treatment of a heel spur is short-term rest and inflammation control. Here are the steps patients should take in order to cure the symptoms of plantar fasciitis and heel spurs. Avoiding the activity that caused the symptoms is the first step in treatment. For example, take a few day off jogging or prolonged standing/walking. Just resting usually helps to eliminate the most severe pain, and will allow the inflammation to begin to cool down. Icing will help to diminish some of the symptoms and control the heel pain. Icing is especially helpful after a sudden flare up of symptoms. Exercises and stretches are designed to relax the tissues that surround the heel bone. Some simple exercises, performed in the morning and evening, often help patients feel better quickly. Many patients will work with a physical therapist, or you can try some simple activities on your own. If you need some help, meet with a therapist for a few sessions to learn a program you can continue on your own.
Usually, heel spurs are curable with conservative treatment. If not, heel spurs are curable with surgery, although there is the possibility of them growing back. About 10% of those who continue to see a physician for plantar fascitis have it for more than a year. If there is limited success after approximately one year of conservative treatment, patients are often advised to have surgery.
In 2002, researchers attempted to compare the effects of various running techniques on pronation and resulting injuries like stress fractures and heel spurs. They suggested that it is possible to teach runners to stride in such a way as to minimize impact forces. One way is to lower running speed. Another is to take longer rest periods following a run.
