The job of the plantar fascia is to aid the footâs bone structure to absorb shock that happens during your gait (walking pattern). Even though it goes against common perception you can have a
high-arch foot and get plantar fasciitis as well as the more common low-arch foot posture associated with PF - tightness doesnât discriminate! The plantar fascia is involved in stabilizing your
foot not only at heel strike, when most people experience pain, but also right through until the foot leaves the ground after the stress has moved from the back of the foot to the big and lesser toes
as you âpush offâ - all this increases the stress on the plantar fascia and not just at the point where it is attached to the heel bone. What most people, even medical professionals, donât
realise is that is has been happening for a long time before it becomes evident (you only notice it when your heel starts to hurt when you stand and move).
Inappropriate footwear is the No. 1 cause of plantar fasciosis. Footwear that possesses toe spring and a tapered toe box holds your big toe in an adducted and extended position. In this position,
your abductor hallucis muscle-the muscle responsible for moving your big toe away from your footâs midline-pulls on a foot structure called the flexor retinaculum and may restrict blood flow
through your posterior tibial artery, the vessel that carries blood to the bottom of your foot. Tissues in the sole of your feet begin to degenerate as blood supply to this area is decreased. Other
recognized causes of or contributors to this health problem include the following, calf muscle shortening, plantar fascia contracture, Obesity, rheumatoid arthritis, reactive arthritis, Psoriatic
arthritis, Corticosteroid injections.
Plantar fasciitis and heel spur pain usually begins in the bottom of the heel, and frequently radiates into the arch. At times, however, the pain may be felt only in the arch. The pain is most
intense when first standing, after any period of rest. Most people with this problem experience their greatest pain in the morning, with the first few steps after sleeping. After several minutes of
walking, the pain usually becomes less intense and may disappear completely, only to return later with prolonged walking or standing. If a nerve is irritated due to the swollen plantar fascia, this
pain may radiate into the ankle. In the early stages of Plantar Fasciitis and Heel Spurs, the pain will usually subside quickly with getting off of the foot and resting. As the disease progresses, it
may take longer periods of time for the pain to subside.
Plantar fasciitis is one of many conditions causing "heel pain". Some other possible causes include nerve compression either in the foot or in the back, stress fracture of the calcaneus, and loss of
the fatty tissue pad under the heel. Plantar fasciitis can be distinguished from these and other conditions based on a history and examination done by a physician. It should be noted that heel spurs
are often inappropriately thought to be the sole cause of heel pain. In fact, heel spurs are common and are nothing more than the bone's response to traction or pulling-type forces from the plantar
fascia and other muscles in the foot where they attach to the heel bone. They are commonly present in patients without pain, and frequently absent from those who have pain. It is the rare patient who
has a truly enlarged and problematic spur requiring surgery.
Non Surgical Treatment
A steroid (cortisone) injection is sometimes tried if your pain remains bad despite the above 'conservative' measures. It may relieve the pain in some people for several weeks but does not always
cure the problem. It is not always successful and may be sore to have done. Steroids work by reducing inflammation. Sometimes two or three injections are tried over a period of weeks if the first is
not successful. Steroid injections do carry some risks, including (rarely) tearing (rupture) of the plantar fascia. Extracorporeal shock-wave therapy. In extracorporeal shock-wave therapy, a machine
is used to deliver high-energy sound waves through your skin to the painful area on your foot. It is not known exactly how it works, but it is thought that it might stimulate healing of your plantar
fascia. One or more sessions of treatment may be needed. This procedure appears to be safe but it is uncertain how well it works. This is mostly because of a lack of large, well-designed clinical
trials. You should have a full discussion with your doctor about the potential benefits and risks. In studies, most people who have had extracorporeal shock-wave therapy have little in the way of
problems. However, possible problems that can occur include pain during treatment, skin reddening, and swelling of your foot or bruising. Another theoretical problem could include the condition
getting worse because of rupture of your plantar fascia or damage to the tissues in your foot. More research into extracorporeal shock-wave therapy for plantar fasciitis is needed. Other treatments.
Various studies and trials have been carried out looking at other possible treatments for plantar fasciitis. Such treatments include injection with botulinum toxin and treatment of the plantar fascia
with radiotherapy. These treatments may not be widely available. Some people benefit from wearing a special splint overnight to keep their Achilles tendon and plantar fascia slightly stretched. The
aim is to prevent the plantar fascia from tightening up overnight. In very difficult cases, sometimes a plaster cast or a removable walking brace is put on the lower leg. This provides rest,
protection, cushioning and slight stretching of the plantar fascia and Achilles tendon. However, the evidence for the use of splint treatment of plantar fasciitis is limited.
The most dramatic therapy, used only in cases where pain is very severe, is surgery. The plantar fascia can be partially detached from the heel bone, but the arch of the foot is weakened and full
function may be lost. Another surgery involves lengthening the calf muscle, a process called gastrocnemius recession. If you ignore the condition, you can develop chronic heel pain. This can change
the way you walk and cause injury to your legs, knees, hips and back. Steroid injections and some other treatments can weaken the plantar fascia ligament and cause potential rupture of the ligament.
Surgery carries the risks of bleeding, infection, and reactions to anesthesia. Plantar fascia detachment can also cause changes in your foot and nerve damage. Gastrocnemius resection can also cause
Being overweight can place excess pressure and strain on your feet, particularly on your heels. Losing weight, and maintaining a healthy weight by combining regular exercise with a healthy, balanced
diet, can be beneficial for your feet. Wearing appropriate footwear is also important. Ideally, you should wear shoes with a low to moderate heel that supports and cushions your arches and heels.
Avoid wearing shoes with no heels.
