Plantar fasciitis is a common and often persistent kind of repetitive strain injury afflicting runners, walkers and hikers, and nearly anyone who stands for a living - cashiers, for instance. It causes mainly foot arch pain and/or heel pain. Morning foot pain is a signature symptom. Plantar fasciitis is not the same thing as heel spurs and flat feet, but they are related and often confused. Most people recover from plantar fasciitis with a little rest, arch support (regular shoe inserts or just comfy shoes), and stretching, but not everyone. Severe cases can stop you in your tracks, undermine your fitness and general health, and drag on for years. This tutorial is mostly for you: the patient with nasty chronic plantar fasciitis that just won’t go away.
Identified risk factors for plantar fasciitis include excessive running, standing on hard surfaces for prolonged periods of time, high arches of the feet, the presence of a leg length inequality, and flat feet. The tendency of flat feet to excessively roll inward during walking or running makes them more susceptible to plantar fasciitis. Obesity is seen in 70% of individuals who present with plantar fasciitis and is an independent risk factor. Studies have suggested a strong association exists between an increased body mass index and the development of plantar fasciitis. Achilles tendon tightness and inappropriate footwear have also been identified as significant risk factors.
The symptoms of plantar fasciitis include pain in the bottom of your foot, especially at the front or centre of the heel bone, pain that is worse when first rising in the morning (called "first-step pain"), when first standing up after any long period of sitting, or after increased levels of activity especially in non-supportive shoes. Seek medical advice about plantar fasciitis if you have heel pain or pain in the bottom of your foot, especially when you get up in the morning, that does not respond to treatment or if there is redness or bruising in the heel.
Your GP or podiatrist (a healthcare professional who specialises in foot care) may be able to diagnose the cause of your heel pain by asking about your symptoms and examining your heel and foot. You will usually only need further tests if you have additional symptoms that suggest the cause of your heel pain is not inflammation, such as numbness or a tingling sensation in your foot, this could be a sign of nerve damage in your feet and legs (peripheral neuropathy) your foot feels hot and you have a high temperature (fever) of 38C (100.4F) or above - these could be signs of a bone infection, you have stiffness and swelling in your heel, this could be a sign of arthritis. Possible further tests may include blood tests, X-rays - where small doses of radiation are used to detect problems with your bones and tissues, a magnetic resonance imaging (MRI) scan or ultrasound scan, which are more detailed scans.
Non Surgical Treatment
Most doctors recommend an initial six- to eight-week program of conservative treatment, including Rest, balanced with stretching exercises to lengthen the heel cord and plantar fascia. Ice massage to the bottom of the foot after activities that trigger heel pain. Avoidance of walking barefoot or wearing slippers or sandals that provide little arch support. A temporary switch to swimming and/or bicycling instead of sports that involve running and jumping. Shoes with soft heels and insoles. Taping the bottom of the injured foot. Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen (Advil, Motrin and other brand names), or acetaminophen (Tylenol) for pain. Physical therapy using ultrasound, electrical stimulation with corticosteroids or massage techniques. If this conservative treatment does not help, your doctor may recommend that you wear a night splint for six to eight weeks. While you sleep, the night splint will keep your foot in a neutral or slightly flexed (bent) position to help maintain the normal stretch of the plantar fascia and heel cord. If the night splint doesn't work, your doctor may inject corticosteroid medication into the painful area or place your foot in a short leg cast for one to three months. Shock wave therapy, in which focused sound energy is applied to the sore heel, may be recommended for plantar fasciitis. The shock waves are intended to irritate or injure the plantar fascia to promote healing. The overall benefit of this approach is uncertain. Other therapies that have been tried include radiation therapy and botulinum toxin injections. But their effectiveness is unclear. If all else fails, your doctor may suggest surgery. But this is rare, and surgery is not always successful.
Most studies indicate that 95% of those afflicted with plantar fasciitis are able to relieve their heel pain with nonsurgical treatments. If you are one of the few people whose symptoms don't improve with other treatments, your doctor may recommend plantar fascia release surgery. Plantar fascia release involves cutting part of the plantar fascia ligament in order to release the tension and relieve the inflammation of the ligament. Overall, the success rate of surgical release is 70 to 90 percent in patients with plantar fasciitis. While the success rate is very high following surgery, one should be aware that there is often a prolonged postoperative period of discomfort similar to the discomfort experienced prior to surgery. This pain usually will abate within 2-3 months. One should always be sure to understand all the risks associated with any surgery they are considering.
