What is Plantar Fasciitis?

Plantar fasciitis is probably the most common cause of heel pain in adults. The plantar fasciia is a large ligament on the underside of the foot. It supports the bones and movement of the foot. Overuse of the plantar fascia, most commonly during weight-bearing activities such as running, or even extended periods of standing can cause small, repetitive tears in the fibers that make up the fascia. The inflammation and swelling that results produces the pain of plantar fasciitis.
