Plantar fasciitis is a painful condition affecting the connective tissue that stretches between the heel and the middle of the foot. It is usually caused by overuse, injury or muscular abnormalities. In extracorporeal shockwave therapy, a machine is used to deliver sound waves to the painful area. It is not known exactly how it works, but it is thought that it might stimulate healing of the fascia.
Because the plantar fascia supports your foot and gets used every time you take a step, it has to absorb a large amount of stress and weight. If too much pressure is put on the plantar fascia, the fibers can become damaged or start to tear. The body responds by causing inflammation in the affected area. This is what causes the pain and stiffness of plantar fasciitis. Things that can increase the risk of plantar fasciitis include tight calf muscles. Tight calves make it harder to flex your foot, and this puts more stress on the plantar fascia. Weight. Carrying a few extra pounds puts added pressure on your feet every time you take a step. Activities that put a lot of stress on the feet. This includes things like running, hiking, dancing, and aerobics. Bad shoes. Footwear that doesn't give your foot the support it needs increases your risk of plantar fasciitis. You'll want to ditch any shoes that have thin soles or inadequate arch support, or ones that don't fit your feet properly. Routinely wearing high heels can also cause your Achilles tendon to contract over time, making it harder to flex your foot. Jobs that involve a lot of standing or walking on hard surfaces. Jobs that keep you on your feet all day, like waiting tables or working in a store, can cause damage to your plantar fascia. High arches, flat feet, or other foot problems. The shape of your foot can affect the way your weight is distributed on your feet when you stand. If weight distribution is a bit off, it can add to a person's risk of plantar fasciitis. How someone walks can increase the stress on certain parts of the foot too.
Plantar fasciitis which usually occurs on one foot at a time typically develops slowly. Some cases can be sudden and severe. If you suspect that you have plantar fasciitis, you should feel a sharp, stabbing heel pain, usually in the inside bottom part of the heel. The pain will likely be worse when you take the first steps after long periods of rest (especially after sleep). The pain may also worsen as you stand, climb stairs, or tiptoe. You typically will not feel a lot of pain during exercise, but will feel the ache after. In some cases, the affected heel may even swell.
After you describe your symptoms and discuss your concerns, your doctor will examine your foot. Your doctor will look for these signs. A high arch, an area of maximum tenderness on the bottom of your foot, just in front of your heel bone. Pain that gets worse when you flex your foot and the doctor pushes on the plantar fascia. The pain improves when you point your toes down. Limited "up" motion of your ankle. Your doctor may order imaging tests to help make sure your heel pain is caused by plantar fasciitis and not another problem. X-rays provide clear images of bones. They are useful in ruling out other causes of heel pain, such as fractures or arthritis. Heel spurs can be seen on an x-ray. Other imaging tests, such as magnetic resonance imaging (MRI) and ultrasound, are not routinely used to diagnose plantar fasciitis. They are rarely ordered. An MRI scan may be used if the heel pain is not relieved by initial treatment methods.
Non Surgical Treatment
A change to properly fitting, appropriate shoes may be useful in some patients. Some individuals wear shoes that are too small, which can exacerbate many types of foot pain. Patients often find that wearing shoes with thicker, well-cushioned midsoles, usually made of a material like high-density ethylene vinyl acetate (such as is found in many running shoes), decreases the pain associated with long periods of walking or standing. Studies have shown that with age, running shoes lose a significant portion of their shock absorption. Thus, simply getting a new pair of shoes may be helpful in decreasing pain. For individuals with flat feet, motion control shoes or shoes with better longitudinal arch support may decrease the pain associated with long periods of walking or standing. Motion control shoes usually have the following characteristics: a straight last, board or combination lasted construction, an external heel counter, a wider flare and extra medial support. A change in shoes was cited by 14 percent of patients with plantar fasciitis as the treatment that worked best for them.
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.
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.
