Plantar Fasciitis is inflammation of the plantar fascia, the connective tissue that runs the length of the bottom of the foot, and is usually caused by standing for long periods of time. If left untreated, bone spurs can form at the attachment point of the fascia on the heel. The bone spurs are typically what cause the heel pain.
There are many treatments for Plantar Fasciitis, including Massage, rest, Heat therapy, orthodics, anti-inflammatories, and as a last resort, surgery. Unfortunately none of these address the cause of the fasciitis.
The "keystone" of the foot is the Talus bone. When the talus is in place, the bones in the foot stay in alignment. If the talus shifts out of place, the rest of the bones in the foot can move. Frequently, when the talus shifts, the calcaneus (heel bone) also shifts. When the calcaneus moves, it pulls the plantar fascia tight across the bottom of your foot. Then, as you walk, the weight of your body on the pulled fascia causes pain.
A Chiropractor trained in extremities adjusting can adjust the bones in your ankle and foot to return the talus and calcaneus to their original positions, taking the pressure off of the plantar fascia. When the fascia is no longer stretched, the pain goes away.
