Hi Dylpup, I hope that this information helps. Plantar fasciitis is caused by the stretching of a tight band of fibrous tissue attached to the bottom of the calcaneus (heel bone), and just behind the toes. Visualize a bow (Bow and arrow) The bow string is similar to the plantar fascia. When extra weight or stress is placed on the fascia it stretches and starts to microtear away from the heel bone. It is the precurser to a heel spur. Walking barefoot puts the most pressure on the fascia at the heel and should be avoided.
It usually comes on insidiously rather than an acute contusion or injury. The inferior aspect of he heel begins to hurt after a vacation, moving, carrying heavy objects, or increasing an exercise program. Being over weight does not help. The classic pain is most acute when one stands up from a chair or car, or getting out of bed. There is less pain once you have walked short distances. One tends to limp on their toes making the calf muscle even tighter. If one has Parkinson related dystonia it compounds the problem.
Treatment:
Wear supportive shoes at all times when walking. Use a clog with a slight heel lift instead of a slipper. Purchase over the counter arch supports (From a hiking or sporting goods store). Custom orthotics from a podiatrist or orthopedist may be necessary. The key is not to let the fasciia or bow string stretch so it can begin to heal itself at the bone.

Stretching the calf and hamstring muscles multiple times daily helps. We use plantar fascia night splints in resistant cases

Cortisone/local anesthesia injections into the heel reduce the pain dramaticly but wear off in one to two weeks. The positives out weigh the negatives and are beneficial for most patients.

Physical therapy can be helpful but expensive. Use Ice rather than heat.

Strapping or taping the arch of the foot helps.

NSAID meds are little benefit. We take enough medication anyway.

A cast or cam walking boot may be used in extreme cases.

Surgery is rarely necessary (1-2%) When conservative therapy is unsucessful,
a soft tissue procedure called a plantar fasciotomy is performed. We rarely remove calcaneal heel spurs anymore.

Make an appointment with a podiatrist or orthopedist. Over 90% of plantar fasciitis patients can be pain free.

There are a few more treatments available,but the above list will cure plantar fasciitis in most patients.

Good Luck, Gary (Podiatrist)
