Plantar fasciitis is the most common cause of heel pain. It can be caused by inadequate or inappropriate footwear, weight gain, or a particular exercise or activity. It is common for plantar
fasciitis symptoms to affect only one foot at a time. Treatment focuses on reducing pain and inflammation. Chronic (long-term) plantar fasciitis can lead to a build-up of bone (a "spur") at the point
where the plantar fascia connects to the heel bone. For this reason plantar fasciitis is sometimes referred to as "heel spur syndrome".
Training on improper, hard and/or irregular surfaces as well as excessive track work in spiked shoes, or steep hill running, can stress the plantar fascia past its limits of elasticity, leading to
injury. Finally, failure in the early season to warm up gradually gives the athlete insufficient time for the structures of the foot to re-acclimate and return to a proper fitness level for intensive
exercise. Such unprepared and repeated trauma causes microscopic tearing, which may only be detected once full-blown plantar fasciitis and accompanying pain and debilitation have resulted. If the
level of damage to the plantar fascia is significant, an inflammatory reaction of the heel bone can produce spike-like projections of new bone, known as heel spurs. Indeed, plantar fasciitis has
occasionally been refereed to as heel spur syndrome, though such spurs are not the cause of the initial pain but are instead a further symptom of the problem. While such spurs are sometimes painless,
in other cases they cause pain or disability in the athlete, and surgical intervention to remove them may be required. A dull, intermittent pain in the heel is typical, sometimes progressing to a
sharp, sustained discomfort. Commonly, pain is worse in the morning or after sitting, later decreasing as the patient begins walking, though standing or walking for long periods usually brings
renewal of the pain.
The typical presentation is sharp pain localized at the anterior aspect of the calcaneus. Plantar fasciitis has a partial association with a heel spur (exostosis); however, many asymptomatic
individuals have bony heel spurs, whereas many patients with plantar fasciitis do not have a spur.
Your doctor will check your feet and watch you stand and walk. He or she will also ask questions about your past health, including what illnesses or injuries you have had. Your symptoms, such as
where the pain is and what time of day your foot hurts most. How active you are and what types of physical activity you do. Your doctor may take an X-ray of your foot if he or she suspects a problem
with the bones of your foot, such as a stress fracture.
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.
Exercises designed to stretch both your calf muscles and your plantar fascia (the band of tissue that runs under the sole of your foot) should help relieve pain and improve flexibility in the
affected foot. A number of stretching exercises are described below. It's usually recommended that you do the exercises on both legs, even if only one of your heels is affected by pain. This will
improve your balance and stability, and help relieve heel pain. Towel stretches. Keep a long towel beside your bed. Before you get out of bed in the morning, loop the towel around your foot and use
it to pull your toes towards your body, while keeping your knee straight. Repeat three times on each foot. Wall stretches. Place both hands on a wall at shoulder height, with one of your feet in
front of the other. The front foot should be about 30cm (12 inches) away from the wall. With your front knee bent and your back leg straight, lean towards the wall until you feel a tightening in the
calf muscles of your back leg. Then relax. Repeat this exercise 10 times before switching legs and repeating the cycle. You should practise wall stretches twice a day. Stair stretches. Stand on a
step of your stairs facing upstairs, using your banister for support. Your feet should be slightly apart, with your heels hanging off the back of the step. Lower your heels until you feel a
tightening in your calves. Hold this position for about 40 seconds, before raising your heels back to the starting position. Repeat this procedure six times, at least twice a day. Chair stretches.
Sit on a chair, with your knees bent at right angles. Turn your feet sideways so your heels are touching and your toes are pointing in opposite directions. Lift the toes of the affected foot upwards,
while keeping the heel firmly on the floor. You should feel your calf muscles and Achilles tendon (the band of tissue that connects your heel bone to your calf muscle) tighten. Hold this position for
several seconds and then relax. Repeat this procedure 10 times, five to six times a day. Dynamic stretches. While seated, roll the arch of your foot (the curved bottom part of the foot between your
toes and heel) over a round object, such as a rolling pin, tennis ball or drinks can. Some people find that using a chilled can from their fridge has the added benefit of helping to relieve pain.
Move your foot and ankle in all directions over the object for several minutes. Repeat the exercise twice a day.
