One of the most common injuries in tennis and jogging, is plantar fascitis, pain on the bottom of the
A band of tissue called the plantar fascia extends from your five toes, along the bottom of your foot
to attach on the bottom of your heel. When you run, you land on your heel and raise yourself on
your toes as you shift your weight to your other foot, causing all your weight to be held up by your
plantar fascia. Such repetitive force can tear the fascia from its attachment on your heel.
Several factors increase force on the fascia, such as shoes that have stiff soles that do not bend in the
right place just behind the ball of your big toe, shoes that are too wide for your feet,/ running too fast
for the present strength of your plantar fascia, or not allowing enough time to recover between fast
workouts. It can also be the first site of pain for arthritis. Doctors have no medications that help heal
the plantar fascia. Cortisone injections and aspirin-like pills can reduce pain, but they can also delay
healing. If you have plantar fascitis, stop running and limit walking until you can run without feeling
pain. Since you pedal with your knees and hips and place little force on your fascia, you can usually
pedal a bicycle without feeling pain. Use shoes that have flexible soles. Wear arch supports that
limit the rolling in motion of your feet, stretch your calf muscles and wear night splints (2,3). Surgery
to cut the plantar, called fasciotomy, is usually ineffective and may even prevent healing 4,5). I have
treated some patients with infractible pain, unconventionally, with 10 mg/day alindronate for three
Some podiatrists now offer a non-surgical treatment for plantar fascitis that does not respond to the conventional treatments. The Food and Drug Administration has approved The Dornier EPOS extracorporeal shockwave machine that has been shown to cure persistent plantar fascitis. If your heel pain has not been cured by other treatments, check with a podiatrist to see whether extracorporeal shockwave treatment is for you.
