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 âfoot tissueâ. 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.
The plantar fascia is designed to absorb the high stresses and strains we place on our feet. But, sometimes, too much pressure damages or tears the tissues. The body's natural response to injury is inflammation, which results in the heel pain and stiffness of plantar fasciitis.
The pain associated with plantar fasciitis is typically gradual in onset and is usually located over the inner or medial aspect of the heel. Occasionally, the pain will be sudden in onset, occurring after missing a step or after jumping from a height. The pain is commonly most severe upon arising from bed in the morning, or after periods of inactivity during the day. Thus, it causes what is known as "first-step pain." The degree of discomfort can sometimes lessen with activity during the course of the day or after "warming-up", but can become worse if prolonged or vigorous activity is undertaken. The pain is also often noted to be more severe in bare feet or in shoes with minimal or no padding at the sole.
A thorough subjective and objective examination from a physiotherapist is usually sufficient to diagnose plantar fasciitis. Occasionally, further investigations such as an X-ray, ultrasound or MRI may be required to assist with diagnosis and assess the severity of the condition.
Non Surgical Treatment
In the early stages of plantar fasciitis resting the foot may ease the pain. Medication to reduce inflammation should help but should only be used short term. Strapping may temporarily reduce the pain. All of the above therapies are only temporary measures and the pain is likely to reoccur if the cause of the abnormal pressure which has triggered the plantar fasciitis has not been identified. In order to establish the cause of the plantar fasciitis a biomechanical assessment may be required.
Most patients have good results from surgery. However, because surgery can result in chronic pain and dissatisfaction, it is recommended only after all nonsurgical measures have been exhausted. The most common complications of release surgery include incomplete relief of pain and nerve damage.
You can help to prevent plantar fasciitis by maintaining a healthy weight, by warming up before participating in sports and by wearing shoes that support the arch and cushion the heel. In people who are prone to episodes of plantar fasciitis, exercises that stretch the heel cord (known as the Achilles tendon) and the plantar fascia may help to prevent plantar fasciitis from returning. Ice massage also can be used on the bottom of the foot after stressful athletic activities. It is possible that strict control of blood sugar will prevent plantar fasciitis in people with diabetes, although this has not been proven.
