Plantar fasciitis is a condition causing heel pain. Supporting the arch, the plantar fascia, a thick band of tissue connecting the heel to the ball of the foot, can become inflamed or can tear. The condition develops when repeated weight-bearing activities put a strain on the plantar fascia. People who are diagnosed with plantar fasciitis also may have heel spurs, a bony growth that forms on the heel bone. However, people with heel spurs may not experience pain.
Plantar fasciitis occurs most frequently in people in their 40s but can occur in all age groups.
The condition can develop in athletes who run a great deal and in non-athletes who are on their feet most of the day, such as police officers, cashiers, or restaurant workers.
Factors that contribute to the development of plantar fasciitis include:
- Age (over 40 years)
- A job, sport, or hobby that involves prolonged standing or other weight-bearing activity
- Rapid increases in length or levels of activity, such as beginning a new running program or changing to a job that requires a lot more standing or walking than you are accustomed to
- Decreased calf muscle flexibility
- Increased body weight (Body Mass Index greater than 30)
- Tendency to have a flat foot (pronation)
Plantar fasciitis affects people of all ages, both athletes and non-athletes. Men and women have an equal chance of developing the condition.
