The plantar fascia is a band of connective tissue that runs along the sole from the heel to the ball of the foot. One of its main roles is to keep the bones and joints in position. Bruising or overstretching this ligament can cause inflammation and heel pain. A common cause is flat feet, because the ligament is forced to overstretch as the foot spreads out and the arch flattens. The pain may be worse first thing in the morning or after rest. In many cases, plantar fasciitis is associated with heel spur. The plantar fascia tears and bleeds at the heel and, over time, these injuries calcify and form a bony growth.
You're more likely to develop the condition if you're female, overweight or have a job that requires a lot of walking or standing on hard surfaces. You're also at risk if you walk or run for exercise, especially if you have tight calf muscles that limit how far you can flex your ankles. People with very flat feet or very high arches also are more prone to plantar fasciitis.
Most patients with plantar fasciitis describe a sharp or stabbing pain on the bottom of the heel that is most severe when they first get up in the morning or after a period of resting. Some may feel like the heel is bruised while others may describe tightness or even a pulling sensation on the heel or arch.
Your doctor will ask you about the kind of pain you're having, when it occurs and how long you've had it. If you have pain in your heel when you stand up for the first time in the morning, you may have plantar fasciitis. Most people with plantar fasciitis say the pain is like a knife or a pin sticking into the bottom of the foot. After you've been standing for a while, the pain becomes more like a dull ache. If you sit down for any length of time, the sharp pain will come back when you stand up again.
Non Surgical Treatment
In general, we start by correcting training errors. This usually requires relative rest, the use of ice after activities, and an evaluation of the patient's shoes and activities. Next, we try correction of biomechanical factors with a stretching and strengthening program. If the patient still has no improvement, we consider night splints and orthotics. Finally, all other treatment options are considered. Non-steroidal anti-inflammatory medications are considered throughout the treatment course, although we explain to the patient that this medicine is being used primarily for pain control and not to treat the underlying problem.
Surgery should be reserved for patients who have made every effort to fully participate in conservative treatments, but continue to have pain from plantar fasciitis. Patients should fit the following criteria. Symptoms for at least 9 months of treatment. Participation in daily treatments (exercises, stretches, etc.). If you fit these criteria, then surgery may be an option in the treatment of your plantar fasciitis. Unfortunately, surgery for treatment of plantar fasciitis is not as predictable as a surgeon might like. For example, surgeons can reliably predict that patients with severe knee arthritis will do well after knee replacement surgery about 95% of the time. Those are very good results. Unfortunately, the same is not true of patients with plantar fasciitis.
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.
