Plantar fasciitis is inflammation of the thick band of tissue that connects to the heel bone.

The exact cause is not known. It is thought to be from repeat trauma from walking or running for long periods.
This problem is most common in people who are 40 to 60 years old. Other things that may raise the risk are:
- Certain foot problems, such as a tight Achilles tendon, flat or high-arched feet, or an ankle that rolls inward too much
- Wearing poor or no footwear
- Activity on hard surfaces
- Spending a lot of time standing
- Not stretching enough
- Poor fitness
Problems may be:
- Mild to severe pain on the sole of the foot near the heel
- Pain that is worse in the morning or after rest
- Pain that worsens with weight-bearing activity
- Pain that gets better with rest
The doctor will ask about your symptoms and health history. A foot exam will be done. This will usually make the diagnosis.
That goal of treatment is to manage symptoms and give the foot time to heal. Options are:
- Supportive care with rest and ice
- A night splint to hold the foot in position while sleeping
- Shoe inserts to support the foot
- Medicines to ease pain and swelling
- Physical therapy to improve function
People with severe problems may need:
- Extracorporeal shock wave therapy
- Surgery to release the plantar fascia
To lower the risk of this problem:
- Wear the right shoes for sports and activities
- Stretch the Achilles tendon and plantar fascia
- Slowly increase the intensity and duration of exercise
- Stay at an appropriate weight
