Understanding Plantar Fasciitis - the Basics

What Is Plantar Fasciitis?

Plantar fasciitis is inflammation of the thick, fibrous band of tissue that reaches from the heel to the toes, supporting the muscles of the bottom of the foot. "Plantar" refers to the bottom of the foot; "fascia" is supportive tissue. When the plantar fascia becomes overly stretched, tiny tears can riddle its surface. The band of fascia can ultimately swell and become quite painful. While some people have attributed this type of pain to bony growths called heel spurs, it's now believed that heel spurs are usually just a coincidental finding in people with plantar fasciitis.

What Causes It?

Plantar fasciitis occurs when the plantar fascia is overly stretched. A number of factors can contribute to this. While men can get plantar fasciitis, it is more common in women. You're also more likely to suffer from this condition as you age or if you:

• Are overweight.
• Take up a new form of exercise or suddenly increase the intensity of your exercise.
• Are on your feet for several hours each day.
• Have other medical conditions, such as rheumatoid arthritis or lupus (systemic lupus erythematosus).
• Tend to wear high-heeled shoes, and then switch abruptly to flat shoes.
• Wear shoes that are worn out, with weak arch supports and thin soles.
• Have flat feet or an unusually high arch.
• Have legs of uneven lengths or an abnormal walk or foot position.
• Have tight achilles tendons, or "heel cords."
