Plantar fasciitis is a common foot disorder that affects more than two million people every year, especially runners. It is inflammation of the plantar fascia, a thick band of tissue on the bottom of the foot. The most common area of pain is directly on the bottom of the heel, although some people may only have pain in the arch of the foot. Diagnosis of plantar fasciitis is typically done through a physical examination, which includes listening to the patient history, palpation of the heel and possibly x-rays.
You're more likely to develop the condition if you're female, overweight or have a job that requires a lot of walking or standing on hard surfaces. You're also at risk if you walk or run for exercise, especially if you have tight calf muscles that limit how far you can flex your ankles. People with very flat feet or very high arches also are more prone to plantar fasciitis.
The main symptom of plantar fasciitis is heel pain when you walk. You may also feel pain when you stand and possibly even when you are resting. This pain typically occurs first thing in the morning after you get out of bed, when your foot is placed flat on the floor. The pain occurs because you are stretching the plantar fascia. The pain usually lessens with more walking, but you may have it again after periods of rest. You may feel no pain when you are sleeping because the position of your feet during rest allows the fascia to shorten and relax.
Your doctor will perform a physical exam to check for tenderness in your foot and the exact location of the pain to make sure that it’s not caused by a different foot problem. The doctor may ask you to flex your foot while he or she pushes on the plantar fascia to see if the pain gets worse as you flex and better as you point your toe. Mild redness or swelling will also be noted. Your doctor will evaluate the strength of your muscles and the health of your nerves by checking your reflexes, your muscle tone, your sense of touch and sight, your coordination, and your balance. X-rays or a magnetic resonance imaging (MRI) scan may be ordered to check that nothing else is causing your heel pain, such as a bone fracture.
Non Surgical Treatment
A number of conservative measures can help take stress off the plantar fascia and encourage healing, including Icing, Taping the arch and bottom of the foot, Stretching, especially the calf, Avoiding walking with bare feet, especially on hard surfaces, Wearing orthotics or arch supports, Taking over-the-counter anti-inflammatories. If these methods fail, we generally try one of two things, A cortisone injection can help reduce swelling. Often a single injection will do the trick, but occasionally a second injection may be needed. Alternatively, we can try extracorporeal pulse activation therapy, or EPAT. This method uses sound waves to penetrate to the plantar fascia and stimulate the body’s healing response. We typically do one treatment a week for three weeks, with complete healing taking between nine to 12 weeks.
Surgery is rarely used in the treatment of plantar fasciitis. However it may be recommended when conservative treatment has been tried for several months but does not bring adequate relief of symptoms. Surgery usually involves the partial release of the plantar fascia from the heel bone. In approximately 75% of cases symptoms are fully resolved within six months. In a small percentage of cases, symptoms may take up to 12 months to fully resolve.
