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. 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.
