Plantar fasciitis is the most common cause of heel pain. Pain from plantar fasciitis is often most noticeable during the first few steps after getting out of bed in the morning. The plantar fascia is
a thick band of tissue in the sole of the foot. Microtearing at the origin of the plantar fascia on the heel bone (calcaneus) can occur with repetitive loading. This microtearing leads to an
inflammatory response (healing response) which produces the pain. Risk factors for plantar fasciitis include excessive standing, increased body weight, increasing age, a change in activity level, and
a stiff calf muscle. Plantar fasciitis can be managed non-operatively in the vast majority of patients. The main components of an effective non-operative treatment program are: calf stretching with
the knee straight, plantar fascia stretching, activity modification (to avoid precipitating activities), and comfort shoe wear.
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.
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 physical exam performed in the office along with the diagnostic studies as an x-ray. An MRI may also be required to rule out a stress fracture, or a tear of the plantar fascia. These are conditions
that do not normally respond to common plantar fasciitis treatment.
Non Surgical Treatment
A doctor may prescribe anti-inflammatory medication such as ibuprofen to help reduce pain and inflammation. Electrotherapy such as ultrasound or laser may also help with symptoms. An X-ray may be
taken to see if there is any bone growth or calcification, known as a heel spur but this is not necessarily a cause of pain. Deep tissue sports massage techniques can reduce the tension in and
stretch the plantar fascia and the calf muscles. Extracorporeal shock wave therapy has been known to be successful and a corticosteroid injection is also an option.
More invasive procedures to treat plantar fasciitis are usually sought only after other treatment has failed to produce favorable results. Corticosteroid injections deliver medicine into the injured
fascia to reduce pain. However, this treatment may weaken the plantar fascia and result in further damage. In addition, extracorporeal shock wave therapy (ESWT) is a treatment where sound waves are
sent through the damaged tissue in order to stimulate the damaged tissue and encourage healing. This method is relatively new in treating plantar fasciitis and your doctor will be able to tell you if
it is the right method for you. Lastly, surgery is the last option for those suffering from chronic or severe plantar fasciitis.
Make sure you wear appropriate supportive shoes. Don't over-train in sports. Make sure you warm up, cool down and undertake an exercise regime that helps maintain flexibility. Manage your weight,
obesity is a factor in causing plantar fasciitis. Avoid walking and running on hard surfaces if you are prone to pain. You should follow the recognized management protocol - RICED-rest, ice,
compression, elevation and diagnosis. Rest, keep off the injured ankle as much as possible. Ice, applied for 20 minutes at a time every hour as long as swelling persists. Compression, support the
ankle and foot with a firmly (not tightly) wrapped elastic bandage. Elevation, keep foot above heart level to minimize bruising and swelling. Diagnosis, Consult a medical professional (such as a
Podiatrist or doctor) especially if you are worried about the injury, or if the pain or swelling gets worse. If the pain or swelling has not gone down significantly within 48 hours, also seek
treatment. An accurate diagnosis is essential for proper rehabilitation of moderate to severe injuries.
