Most people who have plantar fasciitis recover with conservative treatments, including resting, icing the painful area and stretching, in several months.
Pain relievers such as ibuprofen (Advil, Motrin IB, others) and naproxen sodium (Aleve) can ease the pain and inflammation associated with plantar fasciitis.
Stretching and strengthening exercises or use of specialized devices may provide symptom relief. These include:
- Physical therapy. A physical therapist can instruct you in a series of exercises to stretch the plantar fascia and Achilles tendon and to strengthen lower leg muscles, which stabilize your ankle and heel. A therapist might also teach you to apply athletic taping to support the bottom of your foot.
- Night splints. Your physical therapist or doctor might recommend that you wear a splint that stretches your calf and the arch of your foot while you sleep. This holds the plantar fascia and Achilles tendon in a lengthened position overnight and facilitates stretching.
- Orthotics. Your doctor might prescribe off-the-shelf or custom-fitted arch supports (orthotics) to help distribute pressure to your feet more evenly.
Surgical or other procedures
When more-conservative measures aren't working after several months, your doctor might recommend:
- Injections. Injecting a type of steroid medication into the tender area can provide temporary pain relief. Multiple injections aren't recommended because they can weaken your plantar fascia and possibly cause it to rupture. More recently, platelet-rich plasma has been used, under ultrasound guidance, to provide pain relief with less risk of tissue rupture.
- Extracorporeal shock wave therapy. In this procedure, sound waves are directed at the area of heel pain to stimulate healing. It's usually used for chronic plantar fasciitis that hasn't responded to more-conservative treatments. This procedure might cause bruising, swelling, pain, numbness or tingling. Some studies show promising results, but it hasn't been shown to be consistently effective.
- Tenex procedure. This minimally invasive procedure removes the scar tissue of plantar fasciitis without surgery.
- Surgery. Few people need surgery to detach the plantar fascia from the heel bone. It's generally an option only when the pain is severe and all else fails. Side effects include a weakening of the arch in your foot.
