What is Plantar Fasciitis?
Plantar fasciitis is an extremely painful foot injury that commonly occurs in runners and joggers. The plantar muscle in the bottom of the foot can become damaged by the repetitive striking of the foot on the ground. This causes a sharp heel pain to be felt when applying pressure to the affected foot or feet. Luckily there are a variety of methods available to help to cure and prevent plantar fasciitis.
