Heel spurs are usually under the heel and are generally caused by excessive forces acting on the bone. By far the most common cause of heel spurs is abnormal biomechanics - often the same biomechanics that cause plantar fasciitis. Heel spurs are not a direct cause of heel pain. They grow in response to the forces of the soft tissue pulling on the bone. Any condition where the foot has excessive motion can produce tension within the soft tissues acting on the heel.
When a patient has plantar fasciitis, the plantar fascia becomes inflamed and degenerative (worn out)--these abnormalities can make normal activities quite painful. Symptoms typically worsen early in the morning after sleep. At that time, the plantar fascia is tight so even simple movements stretch the contracted plantar fascia. As you begin to loosen the plantar fascia, the pain usually subsides, but often returns with prolonged standing or walking.
Heel spurs may or may not cause symptoms. Symptoms are usually related to the plantar fasciitis. You may experience significant pain. Your heel pain may be worse in the morning when you first wake up or during certain activities.
A thorough history and physical exam is always necessary for the proper diagnosis of heel spurs and other foot conditions. X rays of the heel area are helpful, as excess bone production will be visible.
Non Surgical Treatment
The majority of heel spurs are treated with non-surgical interventions. These can relieve pain, but may take from about 3 months to up to a year for symptoms to resolve. Rest, icing, and over-the-counter anti-inflammatory or prescription medications can help ease symptoms. Cortisone injections may also be used. Physical therapists may instruct you to perform stretching exercises to help relax the tissues in the heel. Your doctor may recommend custom orthotics or shoe inserts to position and cushion your heel. Night splints can help position the heel and arch of the foot while you sleep. Some doctors may recommend extracorporeal shock wave therapy (ESWT). This treatment uses energy pulses to start the repair process in the heel tissues. ESWT is recommend when other non-surgical treatments have failed.
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.
Choose new shoes that are the right size. Have your foot measured when you go to the shoe store instead of taking a guess about the size. Also, try on shoes at the end of the day or after a workout, when your feet are at their largest. To ensure a good fit, wear the same type of socks or nylons that you would normally wear with the type of shoe that you are trying on.
