Plantar fasciitis is a common foot disorder that affects more than two million people every year, especially runners. It is inflammation of the plantar fascia, a thick band of tissue on the bottom of the foot. The most common area of pain is directly on the bottom of the heel, although some people may only have pain in the arch of the foot. Diagnosis of plantar fasciitis is typically done through a physical examination, which includes listening to the patient history, palpation of the heel and possibly x-rays.
Although plantar fasciitis may result from a variety of factors, such as repeat hill workouts and/or tight calves, many sports specialists claim the most common cause for plantar fasciitis is fallen arches. The theory is that excessive lowering of the arch in flat-footed runners increases tension in the plantar fascia and overloads the attachment of the plantar fascia on the heel bone (i.e., the calcaneus). Over time, the repeated pulling of the plantar fascia associated with excessive arch lowering is thought to lead to chronic pain and inflammation at the plantar fascia’s attachment to the heel. In fact, the increased tension on the heel was believed to be so great that it was thought to eventually result in the formation of a heel spur.
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.
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
Check your shoes to make sure they offer sufficient support and motion control. They should bend only at the ball of the foot, where your toes attach to the foot. This is very important. Avoid any shoe that bends in the center of the arch or behind the ball of the foot. It offers insufficient support and will stress your plantar fascia. The human foot was not designed to bend here and neither should a shoe be designed to do this. You may also strengthen the muscles in your arch by performing toe curls or “doming”. Toe curls may be done by placing a towel on a kitchen floor and then curling your toes to pull the towel towards you. This exercise may also be done without the towel against the resistance of the floor. Plantar fasciitis is usually controlled with conservative treatment. Besides surgery and cortisone injections, physical therapy modalities such as electrical stimulation and ultrasound can be used. Often the foot will be taped to limit pronation. Following control of the pain and inflammation an orthotic (a custom made shoe insert) can be used to control over-pronation.
Surgery is usually not needed for plantar fasciitis. About 95 out of 100 people who have plantar fasciitis are able to relieve heel pain without surgery. Your doctor may consider surgery if non-surgical treatment has not helped and heel pain is restricting your daily activities. Some doctors feel that you should try non-surgical treatment for at least 6 months before you consider surgery. The main types of surgery for plantar fasciitis are Plantar fascia release. This procedure involves cutting part of the plantar fascia ligament . This releases the tension on the ligament and relieves inflammation . Other procedures, such as removing a heel spur or stretching or loosening specific foot nerves. These surgeries are usually done in combination with plantar fascia release when there is lasting heel pain and another heel problem. Experts in the past thought that heel spurs caused plantar fasciitis. Now experts generally believe that heel spurs are the result, not the cause, of plantar fasciitis. Many people with large heel spurs never have heel pain or plantar fasciitis. So surgery to remove heel spurs is rarely done.
You may begin exercising the muscles of your foot right away by gently stretching them as follows. Prone hip extension, Lie on your stomach with your legs straight out behind you. Tighten up your buttocks muscles and lift one leg off the floor about 8 inches. Keep your knee straight. Hold for 5 seconds. Then lower your leg and relax. Do 3 sets of 10. Towel stretch, Sit on a hard surface with one leg stretched out in front of you. Loop a towel around your toes and the ball of your foot and pull the towel toward your body keeping your knee straight. Hold this position for 15 to 30 seconds then relax. Repeat 3 times. When the towel stretch becomes too easy, you may begin doing the standing calf stretch. Standing calf stretch, Facing a wall, put your hands against the wall at about eye level. Keep one leg back with the heel on the floor, and the other leg forward. Turn your back foot slightly inward (as if you were pigeon-toed) as you slowly lean into the wall until you feel a stretch in the back of your calf. Hold for 15 to 30 seconds. Repeat 3 times. Do this exercise several times each day. Sitting plantar fascia stretch, Sit in a chair and cross one foot over your other knee. Grab the base of your toes and pull them back toward your leg until you feel a comfortable stretch. Hold 15 seconds and repeat 3 times. When you can stand comfortably on your injured foot, you can begin standing to stretch the bottom of your foot using the plantar fascia stretch. Achilles stretch, Stand with the ball of one foot on a stair. Reach for the bottom step with your heel until you feel a stretch in the arch of your foot. Hold this position for 15 to 30 seconds and then relax. Repeat 3 times. After you have stretched the bottom muscles of your foot, you can begin strengthening the top muscles of your foot. Frozen can roll, Roll your bare injured foot back and forth from your heel to your mid-arch over a frozen juice can. Repeat for 3 to 5 minutes. This exercise is particularly helpful if done first thing in the morning. Towel pickup, With your heel on the ground, pick up a towel with your toes. Release. Repeat 10 to 20 times. When this gets easy, add more resistance by placing a book or small weight on the towel. Balance and reach exercises, Stand upright next to a chair. This will provide you with balance if needed. Stand on the foot farthest from the chair. Try to raise the arch of your foot while keeping your toes on the floor. Keep your foot in this position and reach forward in front of you with your hand farthest away from the chair, allowing your knee to bend. Repeat this 10 times while maintaining the arch height. This exercise can be made more difficult by reaching farther in front of you. Do 2 sets. Stand in the same position as above. While maintaining your arch height, reach the hand farthest away from the chair across your body toward the chair. The farther you reach, the more challenging the exercise. Do 2 sets of 10. Heel raise, Balance yourself while standing behind a chair or counter. Using the chair to help you, raise your body up onto your toes and hold for 5 seconds. Then slowly lower yourself down without holding onto the chair. Hold onto the chair or counter if you need to. When this exercise becomes less painful, try lowering on one leg only. Repeat 10 times. Do 3 sets of 10. Side-lying leg lift, Lying on your side, tighten the front thigh muscles on your top leg and lift that leg 8 to 10 inches away from the other leg. Keep the leg straight. Do 3 sets of 10.
