"What is the treatment of a heel spur?
Treatment of plantar fasciitis is with short-term rest and controlling the inflammation. Avoiding the precipitating activity (e.g. a few day off jogging or prolonged standing/walking), as well as icing, exercises and stretches, and anti-inflammatory medications. These modalities alone will cure the plantar fasciitis pain in most patients. Be forewarned that the symptoms will not resolve quickly. Most patients find relief within about three months, and over 90% within one year.
If the pain does not resolve, an injection of cortisone can decrease the inflammation of the fascia.
Some physicians do not like to do this because there are potentially serious problems with cortisone injections in this area. The two problems that cause concern are fat pad atrophy and plantar fascial rupture. Both of these problems occur in a very small percentage of patients, but they can cause a worsening of heel pain symptoms. "
