Plantar fasciitis is the most common cause of heel pain in runners, eventually affecting 10 percent of the running community. While running, the plantar fascia works with the Achilles tendon to store and return energy. Because of its powerful attachment to the base of the toe, the plantar fascia stabilizes the inner forefoot as forces peak during pushoff. Unlike bone spurs and stress fractures of the heel, plantar fasciitis tends to produce pain during the pushoff phase while running, not during initial contact. A simple way to tell if you have plantar fasciitis versus a heel spur/stress fracture is to walk on your toes: heel spurs and heel stress fractures feel better while you walk on your toes, while plantar fasciitis typically produces more discomfort when you shift your weight onto your toes.
Plantar fasciitis tends to strike those who overtrain, neglect to stretch their calf muscles, or overdo hill work and speedwork. Plantar fasciitis can also be caused by biomechanical flaws, including flat, high-arched feet and a tight Achilles tendon; excessive pronation; sudden increases in training mileage; beginning speedwork; wearing worn running shoes; running on hard surfaces, like asphalt or concrete; or wearing high heels all day before switching into flat running shoes.
When plantar fasciitis occurs, the pain is typically sharp and usually unilateral (70% of cases).Heel pain worsens by bearing weight on the heel after long periods of rest. Individuals with plantar fasciitis often report their symptoms are most intense during their first steps after getting out of bed or after prolonged periods of sitting. Improvement of symptoms is usually seen with continued walking. Numbness, tingling, swelling, or radiating pain are rare but reported symptoms. If the plantar fascia continues to be overused in the setting of plantar fasciitis, the plantar fascia can rupture. Typical signs and symptoms of plantar fascia rupture include a clicking or snapping sound, significant local swelling, and acute pain in the sole of the foot.
A health care professional will ask you whether you have the classic symptoms of first-step pain and about your activities, including whether you recently have intensified your training or changed your exercise pattern. Your doctor often can diagnose plantar fasciitis based on your history and symptoms, together with a physical examination. If the diagnosis is in doubt, your doctor may order a foot X-ray, bone scan or nerve conduction studies to rule out another condition, such as a stress fracture or nerve problem.
Non Surgical Treatment
In general, plantar fasciitis is a self-limiting condition. Unfortunately, the time until resolution is often six to 18 months, which can lead to frustration for patients and physicians. Rest was cited by 25 percent of patients with plantar fasciitis in one study as the treatment that worked best. Athletes, active adults and persons whose occupations require lots of walking may not be compliant if instructed to stop all activity. Many sports medicine physicians have found that outlining a plan of “relative rest” that substitutes alternative forms of activity for activities that aggravate the symptoms will increase the chance of compliance with the treatment plan. It is equally important to correct the problems that place individuals at risk for plantar fasciitis, such as increased amount of weight-bearing activity, increased intensity of activity, hard walking/running surfaces and worn shoes. Early recognition and treatment usually lead to a shorter course of treatment as well as increased probability of success with conservative treatment measures.
In cases that do not respond to any conservative treatment, surgical release of the plantar fascia may be considered. Plantar fasciotomy may be performed using open, endoscopic or radiofrequency lesioning techniques. Overall, the success rate of surgical release is 70 to 90 percent in patients with plantar fasciitis. Potential risk factors include flattening of the longitudinal arch and heel hypoesthesia as well as the potential complications associated with rupture of the plantar fascia and complications related to anesthesia.
Do your best to maintain healthy weight. Plantar fasciitis is caused by wear and tear on your feet. Being overweight drastically increases the pounding your feet take every day. Even losing a few pounds can help reduce heel pain. Avoid jobs that require walking or standing for long periods of time. Having your body weight on your feet all day puts a lot of pressure on your plantar fascia tissue. Replace your shoes on a regular basis. Buy new shoes when the old ones are worn-out. Make sure your shoes will fit your foot size comfortably at the end of the day. Pay attention to the width as well as the length. Use good supportive shoes that will help you with your original problem like arch support, motion control, stability, cushioning etc. Stretch regularly as part of your daily routine. There are a few special stretching techniques for the prevention. Choose soft surfaces for your exercise routine to walk, jog or run on. Rest and elevate your feet every chance you have. Strengthen your foot muscles as part of your exercise routine. Strong foot muscles provide a good support to the plantar fascia. Change your shoes during the work week. Don’t wear the same pair of shoes every day. Perform Warm up exercises such as a short period of walking, a light jog or other easy movement and then stretch before starting the main exercise. Try to avoid dramatic changes in your exercise routine. Increase your exercise level gradually. Don’t run long distance if you are used to walk. Make the change slowly and gradually. Pay attention to your foot pain, do not ignore it. Visit your doctor if the pain continues. Avoid the activities that cause you pain. Use over-the-counter Orthotics or inserts that your doctor may prescribe. Off-the-shelf or custom-fitted arch supports (orthotics) will help distribute pressure to your feet more evenly. Try to avoid barefoot walking, since it may add stress on the plantar fascia ligament.
