Heel pain is a common foot condition. It's usually felt as an intense pain when using the affected heel. Heel pain usually builds up gradually and gets worse over time. The pain is often severe and occurs when you place weight on the heel. In most cases, only one heel is affected, although estimates suggest that around a third of people have pain in both heels. The pain is usually worse first thing in the morning, or when you first take a step after a period of inactivity. Walking usually improves the pain, but it often gets worse again after walking or standing for a long time. Some people may limp or develop an abnormal walking style as they try to avoid placing weight on the affected heel.
Plantar fasciitis is one of those injuries that magically seems to appear for no apparent reason. However, plantar fasciitis is caused by one of two methods. They are either traction or compression injuries. Plantar fasciitis is most often associated with impact and running sports, especially those that involve toe running rather than heel running styles. It is also commonly diagnosed in individuals with poor foot biomechanics that stress the plantar fascia. Flat feet or weak foot arch control muscles are two common causes of plantar fasciitis.
When a patient has plantar fasciitis, the connective tissue that forms the arch of the foot becomes inflamed (tendonitis) and degenerative (tendinosis)--these abnormalities cause plantar fasciitis and can make normal activities quite painful. Symptoms of plantar fasciitis are typically worsened early in the morning after sleep. At that time, the arch tissue is tight and simple movements stretch the contracted tissue. As you begin to loosen the foot, the pain usually subsides, but often returns with prolonged standing or walking.
Your doctor will check your feet and watch you stand and walk. He or she will also ask questions about your past health, including what illnesses or injuries you have had. Your symptoms, such as where the pain is and what time of day your foot hurts most. How active you are and what types of physical activity you do. Your doctor may take an X-ray of your foot if he or she suspects a problem with the bones of your foot, such as a stress fracture.
Non Surgical Treatment
Anti-inflammatory agents used in the treatment of plantar fasciitis include ice, NSAIDs, iontophoresis and cortisone injections. Ice is applied in the treatment of plantar fasciitis by ice massage, ice bath or in an ice pack. For ice massage, the patient freezes water in a small paper or foam cup, then rubs the ice over the painful heel using a circular motion and moderate pressure for five to 10 minutes. To use an ice bath, a shallow pan is filled with water and ice, and the heel is allowed to soak for 10 to 15 minutes. Patients should use neoprene toe covers or keep the toes out of the ice water to prevent injuries associated with exposure to the cold. Crushed ice in a plastic bag wrapped in a towel makes the best ice pack, because it can be molded to the foot and increase the contact area. A good alternative is the use of a bag of prepackaged frozen corn wrapped in a towel. Ice packs are usually used for 15 to 20 minutes. Icing is usually done after completing exercise, stretching, strengthening and after a day's work.
Although most patients with plantar fasciitis respond to non-surgical treatment, a small percentage of patients may require surgery. If, after several months of non-surgical treatment, you continue to have heel pain, surgery will be considered. Your foot and ankle surgeon will discuss the surgical options with you and determine which approach would be most beneficial for you. No matter what kind of treatment you undergo for plantar fasciitis, the underlying causes that led to this condition may remain. Therefore, you will need to continue with preventive measures. Wearing supportive shoes, stretching, and using custom orthotic devices are the mainstay of long-term treatment for 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.
