Overview
Plantar fasciitis, also called “heel pain syndrome,” affects approximately 2 million people in the United States each year. Plantar fasciitis can come on gradually as the result of a degenerative process or sudden foot trauma. It can appear in one heel or both. It is generally worse on taking the first few steps in the morning or after prolonged sitting or non-weight-bearing movement. Symptoms can be aggravated by activity and prolonged weight bearing. Obesity, too, is hard on the feet-it can cause plantar pain or it can make that pain worse. The plantar fascia connects the calcaneal tubercle to the forefoot with five slips directed to each toe respectively. Other conditions, such as calcaneal fat pad atrophy, calcaneal stress fracture, nerve entrapment, and rheumatoid arthritis may also cause foot pain. These conditions may be found in combination with plantar fasciitis, or separate from it. A blood test can help pinpoint the cause(s).
Causes
Causes can be by one or a combination of foot activity overloads. Jogging, climbing, or walking for extended periods puts too much stress on the plantar fascia. But even routine, non-athletic activities such as moving heavy furniture can set off pain. Some kinds of arthritis are also attributed to plantar fasciitis. Certain arthritic conditions cause the tendons of the heel to swell. Diabetes is also a culprit- there is still no explanation why, but studies have repeatedly shown that diabetics are more prone to developing plantar fasciitis. In some cases, plantar fasciitis is triggered by shoes of poor quality or shoes that do not fit. Those with thin soles, no arch support, and no shock-absorbing properties, for example, do not five feet enough protection. Shoes that are too tight and those with very high heels can also cause the Achilles tendon to tighten, straining the tissue surrounding the heels.
Symptoms
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.
Diagnosis
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
Rest the foot as much as you can, especially during the beginning of the treatment. Try to avoid unnecessary foot activity like running, or excess standing. Instead, perform exercises that do not put stress on the injured foot, like bicycling or swimming. Apply ice to the painful area a few times a day to reduce inflammation. Try rolling the arch of the foot over a tennis ball or a baseball. A good treatment is rolling the arch of the foot over a frozen soft drink can. This exercise cools and stretches the affected area. You can use over-the-counter pain relievers (ibuprofen, naproxen) to reduce pain and inflammation. Use an over-the-counter arch support or heel support. Avoid walking barefoot, because it may add stress on the plantar fascia. Exercise your feet to make the muscles, ligaments, tendons and other parts stronger. Stronger foot muscles give better support to the plantar fascia preventing it from another injury. Stretching the foot, the plantar fascia and the calf muscles a few times a day is an essential part of treatment and prevention.
Surgical Treatment
If you consider surgery, your original diagnosis should be confirmed by the surgeon first. In addition, supporting diagnostic evidence (such as nerve-conduction studies) should be gathered to rule out nerve entrapment, particularly of the first branch of the lateral plantar nerve and the medial plantar nerve. Blood tests should consist of an erythrocyte sedimentation rate (ESR), rheumatoid factor, human leukocyte antigen B27 (HLA-B27), and uric acid. It’s important to understand that surgical treatment of bone spurs rarely improves plantar fasciitis pain. And surgery for plantar fasciitis can cause secondary complications-a troubling condition known as lateral column syndrome.
Prevention
While there are no sure ways to prevent plantar fasciitis, these prevention tips may be helpful. Keep your weight under reasonable control. Wear comfortable, supportive shoes. Use care when starting or intensifying exercise programmes.
