Plantar fasciitis is a foot condition that most commonly causes heel pain. It is inflammation and pain of the thick band of tissue that runs across the bottom of your foot, called the plantar fascia. This condition causes stabbing pain that generally occurs in the first few steps in the morning. Pain usually decreases as your foot becomes more limber through the day, but may return after long periods of standing or sitting. It is commonly seen in runners, those who are overweight, pregnant, and those who wear shoes lacking proper support.
The plantar fascia acts as a shock-absorber supporting the arch in the foot. When there is too much tension, it can cause small tears in the fascia. Over time, the fascia becomes irritated and inflamed due to stretching and tearing.
Plantar fasciitis is a sharp pain in the heel of the foot that develops gradually, generally affects one foot, hurts worse with the first steps in the morning, and can be triggered by long periods of standing or standing up from a seated position.
Most people who have plantar fasciitis recover within a few months with help from anti-inflammatory drugs, corticosteroids, physical therapy, night splints, and orthotics. Surgical treatments, although rare, may be indicated.
