What is Plantar Fasciitis? Causes, Symptoms, and Treatment
Our feet help us stand, get from place to place, run, jump, dance and more. That activity relies on a network of bones, muscles, tissues, and nerves that all must work together. When something isn’t quite right, you will typically feel pain.
The heel of the foot is often the site of some pain in many individuals, and often that pain is caused by what is known as plantar fasciitis. More than two million patients receive treatment for plantar fasciitis in the United States each year. About one in 10 people will have heel pain, most commonly plantar fasciitis, in their lifetime.
What is plantar fasciitis?
The plantar fascia is a thick band of fibrous tissue that supports the bottom of the foot along the arch and connects from the heel bone all the way to the toes. If that tissue becomes damaged, it causes pain in the heel.
What causes plantar fasciitis?
Inflammation of the plantar fascia contributes to the pain and swelling. However, the underlying issue is typically more of a degenerative process, with microtears and degeneration of the attachment of the plantar fascia to the heel bone.
This condition can affect adults across the whole age spectrum. There are some factors that increase your risk for developing plantar fasciitis, including:
- tight calf muscles
- prolonged standing
- being overweight
The symptoms of plantar fasciitis
The main symptom of plantar fasciitis is long-term heel pain on the inside bottom of the heel. The pain is usually worse with activity and especially bad with the first few steps getting up from bed or a seated position. Patients often report that ice and anti-inflammatory medications help, but only temporarily.
Effective treatment for plantar fasciitis
Over 90 percent of patients with plantar fasciitis can be successfully treated with conservative treatment. There is evidence that calf stretching as well as dedicated plantar fascia stretching and massage works as well as other treatment. These simple stretches can take six to 12 months to help fully ease the pain of plantar fasciitis.
- Calf stretches can be done in a sitting position with the knee extended and pulling the foot up using a belt. They can also be performed by leaning forward into a wall with the affected leg extended behind and the heel planted – a "runner’s stretch."
- Dedicated plantar fascia stretching involves pulling the foot up and the toes up at the same time to really stretch out the bottom of the foot and then massaging the painful area on the inside of the heel. Regardless of the stretching method, these exercises are most effective if performed consistently and spread out throughout the day.
- Night splints, which hold the foot and toes stretched out at night, can be helpful and are available at most pharmacies.
- An off-the-shelf prefabricated orthotic or insert that is cushioned with an arch support can be helpful in combination with the stretching. These are typically in the $30 to $50 price range.
Treatments to avoid
While stretching, splints and orthotics can help with plantar fasciitis, there are other methods that should be avoided.
- Custom orthotics. There is no evidence to support the use of $300-$500 custom orthotics. Occasionally custom orthotics are indicated, but in general off-the-shelf options that are more economical serve their purpose just as well.
- There is evidence against steroid injections as they are more likely to cause more degeneration or a rupture of the plantar fascia than help.
Surgery for plantar fasciitis - a last resort
There are surgical treatments that can be used to treat plantar fasciitis. The surgery involves cleaning up the degenerative tissue, releasing any adjacent entrapped nerves, and releasing some of the tension in the calf muscles. These surgical options should be reserved as a treatment of last resort after at least six months of active conservative treatments with stretching, splints and/or inserts.
Preventing plantar fasciitis pain
There are things that you can do to reduce your risk of developing plantar fasciitis. Taking the tension off that region of the foot is key.
- Runners, especially when changing exercise regimens or shoe wear, should be diligent about stretching before and after running.
- For people who work standing on their feet, find time to stretch or rest, and wear shoes or orthotics that are comfortable.
- Identifying the symptoms early and treating with stretching can help prevent chronic pain.
