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.
Doing too much running or jumping can inflame the tissue band (fascia) connecting the heel bone to the base of the toes. The pain is centered under the heel and may be mild at first, but flares up when taking the first steps after resting overnight.
Cause & Symptoms
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.
The most common symptoms of plantar fasciitis include:
Pain on the bottom of the foot near the heel
Pain with the first few steps after getting out of bed in the morning, or after a long period of rest, such as after a long car ride. The pain subsides after a few minutes of walking
Greater pain after (not during) exercise or activity
After you describe your symptoms and discuss your concerns, your doctor will examine your foot. Your doctor will look for these signs:
A high arch
An area of maximum tenderness on the bottom of your foot, just in front of your heel bone
Pain that gets worse when you flex your foot and the doctor pushes on the plantar fascia. The pain improves when you point your toes down
Limited “up” motion of your ankle
Your doctor may order imaging tests to help make sure your heel pain is caused by plantar fasciitis and not another problem.
X-rays provide clear images of bones. They are useful in ruling out other causes of heel pain, such as fractures or arthritis. Heel spurs can be seen on an x-ray.
Other Imaging Tests
Other imaging tests, such as magnetic resonance imaging (MRI) and ultrasound, are not routinely used to diagnose plantar fasciitis. They are rarely ordered. An MRI scan may be used if the heel pain is not relieved by initial treatment methods.
