Plantar Fasciitis and Bone Spurs
Plantar fasciitis (fashee-EYE-tiss) is the most common cause of pain on the bottom 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.
The plantar fascia is a ligament that lies beneath the skin on the bottom of your foot.
The plantar fascia 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 inflammation, which results in the heel pain and stiffness of plantar fasciitis.
Too much pressure on the plantar fascia can damage or tear the tissues, causing heel pain.
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 difficult to flex your foot and bring your toes up toward your shin
- Very high arch
- Repetitive impact activity (running/sports)
- New or increased activity
Although many people with plantar fasciitis have heel spurs, spurs are not the cause of plantar fasciitis pain. One out of 10 people has heel spurs, but only 1 out of 20 people (5%) with heel spurs has foot pain. Because the spur is not the cause of plantar fasciitis, the pain can be treated without removing the spur.
Heel spurs do not cause plantar fasciitis pain.
