Plantar fasciitis is an inflammation of the thick connective tissue on the bottom of the foot (plantar fascia) that helps maintain the arches of the foot. The inflammation is due to tearing of the tissue that may not completely repair due to repetitive stress. It is often a precursor to a heel spur. The soles of the feet are very painful, especially in the early morning. Pain with prolonged walking or standing, and toe-walking are also common findings with plantar fascitis. It can be very debilitating, preventing many people from performing normal daily activities or enjoying recreational activities.
Several factors can contribute to plantar fascitis.
