Overview

Plantar fasciitis is pain and inflammation of the plantar fascia, the tissue at the bottom of your foot that connects the heel bone to the toes. The plantar fascia also supports the arch. If you strain the plantar fascia, it can develop small tears and cause heel pain when you stand or walk.

Plantar fasciitis can be caused by running or other sports. It also may occur in people who are overweight or who have high arches or flat feet. You may get plantar fasciitis if you walk or stand for long periods, or have a tight Achilles tendon or calf muscles.

You can improve your foot pain with rest and other care at home. It might take a few weeks to a few months for your foot to heal completely.

How can you care for yourself at home?

• Rest your feet often. Reduce your activity to a level that lets you avoid pain. If possible, do not run or walk on hard surfaces.
• Ask your doctor if you can take an over-the-counter pain medicine, such as acetaminophen (Tylenol), ibuprofen (Advil, Motrin), or naproxen (Aleve). Be safe with medicines. Read and follow all instructions on the label.
• Use ice massage to help with pain. You can use an ice cube or an ice cup several times a day. To make an ice cup, fill a paper cup with water and freeze it. Cut off the top of the cup until a half-inch of ice shows. Hold onto the remaining paper to use the cup. Rub the ice in small circles over the area for 5 to 7 minutes.
• Wear a night splint if your doctor suggests it. A night splint holds your foot with the toes pointed up and the foot and ankle at a 90-degree angle. This position gives the bottom of your foot a constant, gentle stretch.
• Do simple exercises such as calf stretches and marble pickups. Stretches help the plantar fascia become more flexible. Marble pickups help strengthen the muscles that support your arch.
• Wear shoes with good arch support. Athletic shoes or shoes with a well-cushioned sole are good choices.
• Replace athletic shoes regularly.
• Try heel cups or shoe inserts (orthotics) to help cushion your heel. You can buy these at many shoe stores.
• Put on your shoes as soon as you get out of bed. Going barefoot or wearing slippers may make your pain worse.
• Reach and stay at a good weight for your height. This puts less strain on your feet.
