The plantar fascia is made up of 3 distinct parts: the medial, central, and lateral bands. The central plantar fascia is the thickest and strongest section, and this segment is also the most likely to be involved with plantar fasciitis. In normal circumstances, the plantar fascia acts like a windlass mechanism to provide tension and support through the arch. It functions as a tension bridge in the foot, providing both static support and dynamic shock absorption.
Plantar fasciitis symptoms are usually exacerbated via "traction" (or stretching) forces on the plantar fascia. In simple terms, you plantar fascia is repeatedly overstretched. The most common reason for the overstretching are an elongated arch due to either poor foot biomechanics (eg overpronation) or weakness of your foot arch muscles. Compression type plantar fascia injuries have a traumatic history. Landing on a sharp object that bruises your plantar fascia is your most likely truma. The location of plantar fasciitis pain will be further under your arch than under your heel, which is more likely to be a fat pad contusion if a single trauma caused your pain. The compression type plantar fasciitis can confused with a fat pad contusion that is often described as a "stone bruise".
The condition typically starts gradually with mild pain at the heel bone often referred to as a stone bruise. You're more likely to feel it after (not during) exercise. The pain classically occurs right after getting up in the morning and after a period of sitting. If you don't treat plantar fasciitis, it may become a chronic condition. You may not be able to keep up your level of activity, and you may develop symptoms of foot, knee, hip and back problems because plantar fasciitis can change the way you walk.
During the physical exam, your doctor checks for points of tenderness in your foot. The location of your pain can help determine its cause. Usually no tests are necessary. The diagnosis is made based on the history and physical examination. Occasionally your doctor may suggest an X-ray or magnetic resonance imaging (MRI) to make sure your pain isn't being caused by another problem, such as a stress fracture or a pinched nerve. Sometimes an X-ray shows a spur of bone projecting forward 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.
Non Surgical Treatment
No single treatment works best for everyone with plantar fasciitis. But there are many things you can try to help your foot get better. Give your feet a rest. Cut back on activities that make your foot hurt. Try not to walk or run on hard surfaces. To reduce pain and swelling, try putting ice on your heel. Or take an over-the-counter pain reliever like ibuprofen (such as Advil or Motrin) or naproxen (such as Aleve). Do toe stretches camera.gif, calf stretches camera.gif and towel stretches camera.gif several times a day, especially when you first get up in the morning. (For towel stretches, you pull on both ends of a rolled towel that you place under the ball of your foot.) Get a new pair of shoes. Pick shoes with good arch support and a cushioned sole. Or try heel cups or shoe inserts. Use them in both shoes, even if only one foot hurts. If these treatments do not help, your doctor may recommend splints that you wear at night, shots of medicine (such as a steroid) in your heel, or other treatments. You probably will not need surgery. Doctors only suggest it for people who still have pain after trying other treatments for 6 to 12 months. Plantar fasciitis most often occurs because of injuries that have happened over time. With treatment, you will have less pain within a few weeks. But it may take time for the pain to go away completely. It may take a few months to a year. Stay with your treatment. If you don't, you may have constant pain when you stand or walk. The sooner you start treatment, the sooner your feet will stop hurting.
More invasive procedures to treat plantar fasciitis are usually sought only after other treatment has failed to produce favorable results. Corticosteroid injections deliver medicine into the injured fascia to reduce pain. However, this treatment may weaken the plantar fascia and result in further damage. In addition, extracorporeal shock wave therapy (ESWT) is a treatment where sound waves are sent through the damaged tissue in order to stimulate the damaged tissue and encourage healing. This method is relatively new in treating plantar fasciitis and your doctor will be able to tell you if it is the right method for you. Lastly, surgery is the last option for those suffering from chronic or severe plantar fasciitis.
In one exercise, you lean forward against a wall with one knee straight and heel on the ground. Your other knee is bent. Your heel cord and foot arch stretch as you lean. Hold for 10 seconds, relax and straighten up. Repeat 20 times for each sore heel. It is important to keep the knee fully extended on the side being stretched. In another exercise, you lean forward onto a countertop, spreading your feet apart with one foot in front of the other. Flex your knees and squat down, keeping your heels on the ground as long as possible. Your heel cords and foot arches will stretch as the heels come up in the stretch. Hold for 10 seconds, relax and straighten up. Repeat 20 times. About 90 percent of people with plantar fasciitis improve significantly after two months of initial treatment. You may be advised to use shoes with shock-absorbing soles or fitted with an off-the-shelf shoe insert device like a rubber heel pad. Your foot may be taped into a specific position. If your plantar fasciitis continues after a few months of conservative treatment, your doctor may inject your heel with steroidal anti-inflammatory medication. If you still have symptoms, you may need to wear a walking cast for two to three weeks or a positional splint when you sleep. In a few cases, surgery is needed for chronically contracted tissue.
