Foot pain affects nearly all people at one time or another. It can also lead to other musculoskeletal problems such as ankle, knee and back pain (Hill et al., 2008). This pain negatively affects one’s quality of life and ability to enjoy workouts and/or maintain a regular program of exercise. One of the most common sources of foot pain is plantar fasciitis, a condition where the connective tissue on the underside of the foot becomes irritated and painful as a result of an injury, overuse or misuse. The plantar fascia is a system of connective tissue that runs from your heel to just behind your toes. During weightbearing activities, such as walking or running, your body weight is transferred onto your foot from your heel to your toes (which results in your toes moving away from your heel). This spreading out of the foot places tension on the plantar fascia because it connects those two parts. If the tension on this structure is too great or is not dispersed evenly, the plantar fascia can develop microtears and become irritated and painful, resulting in a condition called plantar fasciitis.
Plantar fasciitis is a painful disorder in the lower part of your foot usually around the heel. That pain usually hurts as you get up in the morning when you try to stand on your feet, or after any periods of inactivity. It is a disorder of a tough and strong band that connects the heel bone to the toes. Plantar Fasciitis is caused by injuring that tough band on the bottom of the foot. The following may be the causes of plantar fasciitis. Tight calf muscles or tight Achilles tendon produces repetitive over-stretching of the plantar fascia. Gait and balance Problem may be a dominant cause of this disorder. Many people have a special style of walking, with something unique that causes some kind of imbalance in their body. It might be something like locked knees, feet that turn-out, a weak abdomen etc. This imbalance may place some pressure on the fascia, which eventually causes plantar fasciitis. Weak foot muscles don’t give enough support to the plantar fascia. The small muscles in the foot give the foot its shape by keeping the bones in place and by expanding and contracting to make a movement. Weak foot muscles will allow greater stress on the fascia. Foot anatomical problems such as flat feet or high arches can make the fascia ligament work or stretch abnormally. Flattening of the fat pad at the sole of the feet under the heels is a Degeneration process that is caused by poor footwear or by age. Shoes that have no proper heel cup can flatten that fat pad quite quickly and cause this disorder. Walking in shoes which do not have good arch support is considered to be a cause of plantar fasciitis. Wearing inadequate or worn out shoes may place more stress on the fascia ligament. If you wear shoes that don’t fit you by size or width, you may put your feet under excessive stress. Overweight Men and women are more vulnerable to developing the condition because of the excess weight on the foot. Pregnant women are at risk due to gaining weight through pregnancy and due to the pregnancy hormones that make ligaments loosen and relax. Sudden increase of activity like starting to run long distance or complete change of daily activity can cause heel pain and this disorder. Practice of repetitive athletic activities, like long distance running, playing a ball game, dancing or jumping, is a common cause for the disorder. Actually it is considered as one of the most common running injuries. Spending long periods of time on your feet everyday can cause plantar fasciitis. Working on your feet a few hours a day evey day may be the reason for your heel pain.
Pain is the main symptom. This can be anywhere on the underside of your heel. However, commonly, one spot is found as the main source of pain. This is often about 4 cm forward from your heel, and may be tender to touch. The pain is often worst when you take your first steps on getting up in the morning, or after long periods of rest where no weight is placed on your foot. Gentle exercise may ease things a little as the day goes by, but a long walk or being on your feet for a long time often makes the pain worse. Resting your foot usually eases the pain. Sudden stretching of the sole of your foot may make the pain worse, for example, walking up stairs or on tiptoes. You may limp because of pain. Some people have plantar fasciitis in both feet at the same time.
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
Over-the-counter Orthotics. A soft, over-the-counter orthotic (Prefabricated orthotic) with an accommodating arch support has proven to be quite helpful in the management of plantar fascia symptoms. Studies demonstrate that it is NOT necessary to obtain a custom orthotic for the treatment of this problem. Comfort Shoes. Shoes with a stiff sole, rocker-bottom contour, and a comfortable leather upper combined with an over-the-counter orthotic or a padded heel can be very helpful in the treatment of plantar fasciitis. Anti-Inflammatory Medication (NSAIDs): A short course of over-the-counter anti-inflammatory medications may be helpful in managing plantar fasciitis symptoms providing the patient does not have any contra-indications such as a history of stomach ulcers. Activity Modification Any activity that has recently been started, such as a new running routine or a new exercise at the gym that may have increased loading through the heel area, should be stopped on a temporary basis until the symptoms have resolved. At that point, these activities can be gradually started again. Also, any activity changes (ex. sitting more) that will limit the amount of time a patient is on their feet each day may be helpful. A night splint, which keeps the ankle in a neutral position (right angle) while the patient sleeps, can be very helpful in alleviating the significant morning symptoms. A night splint may be prescribed by your physician. Alternatively, it can be ordered online or even obtained in some medical supply stores. This splint is worn nightly for 1-3 weeks until the cycle of pain is broken. Furthermore, this splinting can be reinstituted for a short period of time is symptoms recur.
The most common surgical procedure for plantar fasciitis is plantar fascia release. It involves surgical removal of a part from the plantar fascia ligament which will relieve the inflammation and reduce the tension. Plantar fascia release is either an open surgery or endoscopic surgery (insertion of special surgical instruments through small incisions). While both methods are performed under local anesthesia the open procedure may take more time to recover. Other surgical procedures can be used as well but they are rarely an option. Complications of plantar fasciitis surgery are rare but they are not impossible. All types of plantar fasciitis surgery pose a risk of infection, nerve damage, and anesthesia related complications including systemic toxicity, and persistence or worsening of heel pain.
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.
