One of the main symptoms of plantar fasciitis is foot arch pain. Other plantar fascia symptoms include pain in ball of foot, and pain in heel. Plantar fasciitis is an inflammatory injury to the tight band of ligamentous tissue along the bottom of the foot. The plantar fascia acts like a spring on the bottom of the foot, and extends from the heel to the ball, creating the foot’s arch.
One of the most common ways the plantar fascia becomes injured is by running. Also, people who stand and walk a lot at work may develop it as well; it can happen in one or both feet. The fasica is responsible for bearing a lot of our bodily weight. When the demands on it out weight rest (such as running or standing all days for several days in a row), it becomes inflamed and painful. "Itis" simply means the plantar tissue is inflamed.
