What Can Cause Plantar Fasciitis

Plantar Fasciitis

Overview

If you experience sharp, throbbing or aching heel pain with your first steps out of bed each morning, or when walking throughout the day, you may be suffering from Plantar Fasciitis. This guide will help you to understand the definition, symptoms and causes of this condition and will explore your treatment options for rapid relief from your pain.




Causes

Each time we take a step forward, all of our body weight first rests on the heel of one foot. As our weight moves forward, the entire foot begins to bear the body's weight, and the foot flattens and this places a great deal of pressure and strain on the plantar fascia. There is very little elasticity to the plantar fascia, so as it stretches only slightly; it pulls on its attachment to the heel. If the foot is properly aligned this pull causes no problems. However, if the foot is "pronated" (the foot rolls outward at the ankle, causing a break down of the inner side of the shoe), the arch falls excessively, and this causes an abnormal stretching of the relatively inflexible plantar fascia, which in turn pulls abnormally hard on the heel. The same pathology occurs with "supination" (the rolling inward of the foot, causing a break down of the outer side of the shoe). Supinated feet are relatively in flexible; usually have a high arch, and a short or tight plantar fascia. Thus as weight is transferred from the heel to the remainder of the foot, the tight plantar fascia hardly stretches at all, and pulls with great force on its attachment to the heel.




Symptoms

A sharp pain in the center of your heel will most likely be one of the biggest symptoms of plantar fasciitis. A classic sign of plantar fasciitis is when the pain is worst during the first steps you take in the morning.




Diagnosis

Plantar fasciitis is usually diagnosed by your physiotherapist or sports doctor based on your symptoms, history and clinical examination. After confirming your plantar fasciitis they will investigate WHY you are likely to be predisposed to plantar fasciitis and develop a treatment plan to decrease your chance of future bouts. X-rays may show calcification within the plantar fascia or at its insertion into the calcaneus, which is known as a calcaneal or heel spur. Ultrasound scans and MRI are used to identify any plantar fasciitis tears, inflammation or calcification. Pathology tests (including screening for HLA B27 antigen) may identify spondyloarthritis, which can cause symptoms similar to plantar fasciitis.




Non Surgical Treatment

Treatment of plantar fasciitis begins with first-line strategies, which you can begin at home. Stretching exercises. Exercises that stretch out the calf muscles help ease pain and assist with recovery. Avoid going barefoot. When you walk without shoes, you put undue strain and stress on your plantar fascia. Ice. Putting an ice pack on your heel for 20 minutes several times a day helps reduce inflammation. Place a thin towel between the ice and your heel,do not apply ice directly to the skin. Limit activities. Cut down on extended physical activities to give your heel a rest. Shoe modifications. Wearing supportive shoes that have good arch support and a slightly raised heel reduces stress on the plantar fascia. Medications. Oral nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, may be recommended to reduce pain and inflammation. If you still have pain after several weeks, see your foot and ankle surgeon, who may add one or more of these treatment approaches. Padding and strapping. Placing pads in the shoe softens the impact of walking. Strapping helps support the foot and reduce strain on the fascia. Orthotic devices. Custom orthotic devices that fit into your shoe help correct the underlying structural abnormalities causing the plantar fasciitis. Injection therapy. In some cases, corticosteroid injections are used to help reduce the inflammation and relieve pain. Removable walking cast. A removable walking cast may be used to keep your foot immobile for a few weeks to allow it to rest and heal. Night splint. Wearing a night splint allows you to maintain an extended stretch of the plantar fascia while sleeping. This may help reduce the morning pain experienced by some patients. Physical therapy. Exercises and other physical therapy measures may be used to help provide relief.

Surgical Treatment

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.




Stretching Exercises

Exercises designed to stretch both your calf muscles and your plantar fascia (the band of tissue that runs under the sole of your foot) should help relieve pain and improve flexibility in the affected foot. A number of stretching exercises are described below. It's usually recommended that you do the exercises on both legs, even if only one of your heels is affected by pain. This will improve your balance and stability, and help relieve heel pain. Towel stretches. Keep a long towel beside your bed. Before you get out of bed in the morning, loop the towel around your foot and use it to pull your toes towards your body, while keeping your knee straight. Repeat three times on each foot. Wall stretches. Place both hands on a wall at shoulder height, with one of your feet in front of the other. The front foot should be about 30cm (12 inches) away from the wall. With your front knee bent and your back leg straight, lean towards the wall until you feel a tightening in the calf muscles of your back leg. Then relax. Repeat this exercise 10 times before switching legs and repeating the cycle. You should practise wall stretches twice a day. Stair stretches. Stand on a step of your stairs facing upstairs, using your banister for support. Your feet should be slightly apart, with your heels hanging off the back of the step. Lower your heels until you feel a tightening in your calves. Hold this position for about 40 seconds, before raising your heels back to the starting position. Repeat this procedure six times, at least twice a day. Chair stretches. Sit on a chair, with your knees bent at right angles. Turn your feet sideways so your heels are touching and your toes are pointing in opposite directions. Lift the toes of the affected foot upwards, while keeping the heel firmly on the floor. You should feel your calf muscles and Achilles tendon (the band of tissue that connects your heel bone to your calf muscle) tighten. Hold this position for several seconds and then relax. Repeat this procedure 10 times, five to six times a day. Dynamic stretches. While seated, roll the arch of your foot (the curved bottom part of the foot between your toes and heel) over a round object, such as a rolling pin, tennis ball or drinks can. Some people find that using a chilled can from their fridge has the added benefit of helping to relieve pain. Move your foot and ankle in all directions over the object for several minutes. Repeat the exercise twice a day.
