Definition

Causes

Plantar fasciitis is caused by small, repetitive trauma to the plantar fascia. This trauma can be due to activity that puts extra stress on the foot.

Risk Factors

Plantar fasciitis is most common in people who are 40-60 years old. Other risk factors that increase your chance of getting plantar fasciitis include:

  • Physical exertion, especially in sports such as:
    • Running
    • Volleyball
    • Tennis
  • A sudden increase in exercise intensity or duration
  • Physical activity that stresses the plantar fascia
  • People who spend a lot of time standing
  • A sudden increase in activities that affect the feet
  • Obesity or weight gain
  • Pre-existing foot problems, including an abnormally tight Achilles tendon, flat feet, or an ankle that rolls inward too much
  • Poor footwear
  • Heel spurs

Symptoms

Symptoms of plantar fasciitis may start gradually or happen suddenly. They include:

  • Pain on the sole of the foot near the heel
  • Heel pain when taking the first steps in the morning
  • Tenderness when touching the sole or heel
  • Pain that increases over a period of months

Diagnosis

You will be asked about your symptoms and medical history. A foot exam will be done. This will usually make the diagnosis.

Imaging studies of the foot may be done to help rule out stress fractures or other bone abnormalities. These include:

Treatment

Talk to your doctor about the best treatment plan for you. Options include:

Supportive Care

Your foot will need time to heal. Supportive care may include:

  • Rest—Activities, such as running, may need to be restricted.
  • Ice—Ice therapy may help relieve pain.
  • Night splint—A night splint helps to hold the foot in a neutral position while sleeping.
  • Orthotics—Special shoe inserts will help to support the mid-arch region of the foot.

Stretches to lengthen the Achilles tendon and plantar fascia may be advised when pain has lessened.

Over-the-counter or prescription pain medication may be advised. Steroid injections may also be used in some cases if other treatments do not provide relief.

Procedures

A special type of sound wave called extracorporeal shock wave may also be considered in certain cases. This treatment happens under the care of your doctor. At this time, this is generally a treatment for long-term cases that do not respond to other treatments. Massage therapy or acupuncture may also be effective for long-term cases.

Surgery

In a few cases, basic treatments don't help. Surgery may be performed to cut the tight, swollen fascia.

Prevention

To reduce your risk of getting plantar fasciitis take these steps:

  • Wear appropriate and well-fitted footwear during sports and exercise.
  • Do stretching exercises for the Achilles tendon and plantar fascia.
  • Increase the intensity and duration of exercise gradually.
  • Maintain an appropriate weight.
