Plantar Fasciitis
The plantar fascia is a thick, fibrous tissue on the bottom of the foot, attached to the heel bone and fanning toward the toe. It is responsible for maintaining the arch of the foot. Pain can result when these tissues become irritated or inflamed from repetitive stress. Plantar fascia injuries may occur in the heel or mid-arch or even towards the toes.
Sometimes, as the fascia is pulled away from the bone, the body fills the space with new bone, causing small ‘heel spurs.’ This projection of bone can grow where the foot muscles attach to the bone.
People with flat, pronated, or high-arched rigid feet may be more predisposed to this injury. It is important to note that a painful heel may also accompany gout, arthritis, nerve injuries, psoriasis, heel bone abnormalities, collagen disorders, or tumours. Illnesses like these and others must be diagnosed and treated separately.
