What Is Plantar Fasciitis

Overview

Plantar fasciitis is a dull to severe pain in your heel caused by a strain and inflammation of your plantar fascia. The plantar fascia is a scientific name for “foot tissue”. This particular tissue is a ligament attached at one side to the heel bone. At the other side, the tissue fans out to attach at the base of each of your five toes. Plantar fasciitis is the name for the condition that develops when that tissue becomes inflamed. When the plantar fascia is excessively stretched, micro-tears can occur, causing this swelling and subsequent pain.




Causes

When the foot moves, the plantar fascia stretches and contracts. Plantar fasciitis is caused by the repetitive overstretching of the plantar fascia. If the tension on the plantar fascia is too great, this overstretching causes small tears in the plantar fascia. This in turn causes the plantar fascia to become inflamed and painful. Factors that contribute to the development of plantar fasciitis include having very high arches or flat feet, gender, while anyone can develop plantar fasciitis, it tends to occur more commonly in women, exercises such as running, walking and dancing, particularly if the calf muscles are tight. Activities or occupations that involve walking or standing for long periods of time, particularly on hard surfaces, wearing high heeled shoes or shoes that do not offer adequate arch support and cushioning, being overweight, additional weight increases the tension on the plantar fascia, poor biomechanics, extra tension is placed on the plantar fascia if weight is not spread evenly when standing, walking or running. Some cases of plantar fasciitis may be linked to underlying diseases that cause arthritis, such as ankylosing spondylitis.




Symptoms

You'll typically first notice early plantar fasciitis pain under your heel or in your foot arch in the morning or after resting. Your heel pain will be worse with the first steps and improves with activity as it warms up. As plantar fasciitis deteriorates, the pain will be present more often. You can determine what stage your are in using the following guidelines. No Heel Pain, Normal! Heel pain after exercise. Heel pain before and after exercise. Heel pain before, during and after exercise. Heel pain all the time. Including at rest! This symptom progression is consistent with the four stages of a typical overuse injury. Ultimately, further trauma and delayed healing will result in the formation of calcium (bone) within the plantar fascia. When this occurs adjacent to the heel bone it is known as heel spurs, which have a longer rehabilitation period.




Diagnosis

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

The key for the proper treatment of plantar fasciitis is determining what is causing the excessive stretching of the plantar fascia. When the cause is over-pronation (flat feet), an orthotic with rearfoot posting and longitudinal arch support is an effective device to reduce the over-pronation and allow the condition to heal. If you have usually high arches, which can also lead to plantar fasciitis, cushion the heel, absorb shock and wear proper footwear that will accommodate and comfort the foot. Other common treatments include stretching exercises, plantar fasciitis night splints, wearing shoes that have a cushioned heel to absorb shock, and elevating the heel with the use of a heel cradle or heel cup. Heel cradles and heel cups provide extra comfort, cushion the heel, and reduce the amount of shock and shear forces placed during everyday activities.






Surgical Treatment

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.




Prevention

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.
