Plantar fasciitis is characterized by stiffness and inflammation of the main fascia (fibrous connective [ligament-like] tissue) on the bottom of the foot. It is occasionally associated with a bone
spur on the heel. Occasionally there may be a partial or complete tear of the fascia of the bottom of the foot. Bone spurs themselves usually do not cause symptoms.
Plantar Fasciitis is caused by abnormal pronation of the foot. Contributing factors are obesity, weight gain, jobs that require a lot of walking or standing on hard surfaces, badly worn shoes with
little support, and also inactivity. As a result of over-pronation, with every step the Plantar Fascia (band of tissue under the foot) is being stretched, resulting in inflammation, irritation and
pain at the attachment of the fascia into the heel bone. In some cases the pain is felt under the foot, in the arch. Continuous pulling of the fascia at the heel bone, eventually may lead to the
development of bony growth on the heel. This is called a heel spur. When youâre at rest, such as while sleeping, the Plantar Fascia tightens and shortens. When body weight is rapidly applied to the
foot, the Fascia must stretch and quickly lengthen, causing micro-tears in the Fascia. As a result, the foot pain is more severe with your first steps in the morning, or after sitting for a long
period. Plantar Fasciitis is more likely to happen if you suffer from over-pronation (flattening of the arch), you stand or walk on hard surfaces, for long periods, you are overweight or pregnant,
you have tight calf muscles.
The classic sign of plantar fasciitis is that the worst pain occurs with the first few steps in the morning, but not every patient will have this symptom. Patients often notice pain at the beginning
of activity that lessens or resolves as they warm up. The pain may also occur with prolonged standing and is sometimes accompanied by stiffness. In more severe cases, the pain will also worsen toward
the end of the day.
Your GP or podiatrist (a healthcare professional who specialises in foot care) may be able to diagnose the cause of your heel pain by asking about your symptoms and examining your heel and foot. You
will usually only need further tests if you have additional symptoms that suggest the cause of your heel pain is not inflammation, such as numbness or a tingling sensation in your foot, this could be
a sign of nerve damage in your feet and legs (peripheral neuropathy) your foot feels hot and you have a high temperature (fever) of 38C (100.4F) or above - these could be signs of a bone infection,
you have stiffness and swelling in your heel, this could be a sign of arthritis. Possible further tests may include blood tests, X-rays - where small doses of radiation are used to detect problems
with your bones and tissues, a magnetic resonance imaging (MRI) scan or ultrasound scan, which are more detailed scans.
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.
In unusual cases, surgical intervention is necessary for relief of pain. These should only be employed after non-surgical efforts have been used without relief. Generally, such surgical procedures
may be completed on an outpatient basis in less than one hour, using local anesthesia or minimal sedation administrated by a trained anesthesiologist. In such cases, the surgeon may remove or release
the injured and inflamed fascia, after a small incision is made in the heel. A surgical procedure may also be undertaken to remove bone spurs, sometimes as part of the same surgery addressing the
damaged tissue. A cast may be used to immobilize the foot following surgery and crutches provided in order to allow greater mobility while keeping weight off the recovering foot during healing. After
removal of the cast, several weeks of physical therapy can be used to speed recovery, reduce swelling and restore flexibility.
Stretching the plantar fascia and the calf muscle area can help to prevent inflammation. Slowly increasing the amount or intensity of athletic activities by graded progression can also help to
prevent injury. Recommended Stretches: Taking a lunge position with the injured foot behind and keeping your heels flat on the floor, lean into a wall and bend the knees. A stretch should be felt in
the sole and in the Achilles tendon area. Hold the stretch for 20-30 seconds. Also try this stretch with the back leg straight.
