Plantar Fasciitis Overview
Plantar fasciitis (PLAN-tur fas-e-I-tis) is one of the most common causes of heel pain. It involves inflammation of a thick band of tissue that runs across the bottom of your foot and connects your heel bone to your toes (plantar fascia).
Plantar fasciitis commonly causes stabbing pain that usually occurs with your first steps in the morning. As you get up and move, the pain normally decreases, but it might return after long periods of standing or when you stand up after sitting
Plantar Fasciitis Symptoms
Plantar fasciitis typically causes a stabbing pain in the bottom of your foot near the heel. The pain is usually the worst with the first few steps after awakening, although it can also be triggered by long periods of standing or when you get up after sitting. The pain is usually worse after exercise, not during it.
Plantar Fasciitis Diagnosis
Plantar fasciitis is diagnosed based on your medical history and physical examination. During the exam, your doctor will check for areas of tenderness in your foot. The location of your pain can help determine its cause.
Usually no tests are necessary. Your doctor might suggest an X-ray or magnetic resonance imaging (MRI) to make sure another problem, such as a stress fracture, is not causing you pain.
Sometimes an X-ray shows a piece of bone sticking out (spur) from the heel bone. In the past, these bone spurs were often blamed for heel pain and removed surgically. But many people who have bone spurs on their heels have no heel pain.
Plantar Fasciitis Treatment
Pain relievers such as ibuprofen (Advil, Motrin IB, others) and naproxen sodium (Aleve) may ease the pain and inflammation caused by plantar fasciitis.
Stretching and strengthening exercises or using special devices may relieve symptoms. They include:
A physical therapist can show you a series of exercises to stretch the plantar fascia and Achilles tendon and to strengthen lower leg muscles. A therapist might also teach you to apply athletic taping to support the bottom of your foot.
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 to promote stretching.
Your doctor might prescribe custom-fitted arch supports (orthotics) to help distribute pressure to your feet more evenly.
Surgical or other procedures
If more-conservative measures aren’t working after several months, your doctor might recommend:
Platelet-rich plasma obtained from the patient’s own blood can be injected to promote tissue healing.
Ultrasonic tissue repair.
This minimally invasive technology uses ultrasound imaging to guide a needlelike probe into the damaged plantar fascia tissue. Using ultrasound energy, the probe tip vibrates rapidly to break up the damaged tissue, which is then suctioned out.
Few people need surgery to detach the plantar fascia from the heel bone. It is generally an option only when the pain is severe and other treatments have failed. It can be done as an open procedure or through a small incision with local anesthesia.
