Plantar Fasciitis OverviewThe fibrous tissue that surrounds muscle and separates various tissues of the body is referred to as the fascia. The bottom, or plantar, surface of the foot has a strip of this tough tissue, referred to as the plantar fascia, stretching from the heel to the front of the bottom of the foot. This "bowstring-like" plantar fascia that stretches underneath the sole that attaches at the heel can become inflamed by disease or injury. Inflammation of the plantar fascia is referred to as plantar fasciitis.
Plantar Fasciitis CausesPlantar fasciitis most commonly occurs in people between 40 and 60 years of age. Plantar fasciitis can occur alone from injury or may be related to underlying diseases that cause arthritis (inflammation of the joints) such as reactive arthritis (formerly called Reiter's disease), ankylosing spondylitis, and diffuse idiopathic skeletal hyperostosis. Sometimes plantar fasciitis occurs for unknown reasons. |

It supports the arch of your foot. If you strain your plantar fascia, it gets weak, swollen, and irritated (inflamed). Then your heel or the bottom of your foot hurts when you stand or walk.
Plantar fasciitis is common in middle-aged people. It also occurs in younger people who are on their feet a lot, like athletes or soldiers. It can happen in one foot or both feet.
What causes plantar fasciitis?
Plantar fasciitis is caused by straining the ligament that supports your arch. Repeated strain can cause tiny tears in the ligament. These can lead to pain and swelling. This is more likely to happen if:
