Plantar Fasciitis

Plantar fasciitis is inflammation in the plantar fascia in your foot. It’s the most common cause of heel pain.

The plantar fascia is a strong, fibrous attachment (similar to a ligament) that runs from your heel to the ball of your foot and your toes. It’s stretchy like a thick rubber band. The plantar fascia connects the bones in your foot together and forms the arch on the bottom of your foot.

Plantar fasciitis happens when your plantar fascia is overused or stretched too far. Anything that damages your plantar fascia can make it swell. This inflammation makes it painful to walk or use your foot. Most people experience plantar fasciitis in one foot at a time, but it’s possible for it to affect both your feet at once.

Visit a healthcare provider if you’re experiencing heel or foot pain for more than a week.
