Plantar fasciitis (fashee-EYE-tiss) is the most common cause of pain on the botton of the heel. Approximately 2 million patients are treated for this condition every year. Plantar fasciitis occurs when the strong band of tissue that supports the arch of your foot becomes irritated and inflamed.
The plantar fascia is a long, thin ligament that lies directly beneath the skin on the bottom of your foot. It connects the heel to the front of your foot, and supports the arch of your foot. It is designed to absorb the high stresses and strains we place on our feet. But, sometimes, too much pressure damages or tears the tissues. The body’s natural response to injury is in ammation, which results in the heel pain and stiffness of plantar fasciitis.
In most cases, plantar fasciitis develops without a specific, identifiable reason. There are, however, many factors that can make you more prone to the condition:
- Tighter calf muscles that make it dif cult to ex your foot and bring your toes up toward your shin - Obesity
- Very high arch
- Repetitive impact activity (running/sports)
- New or increased activity
