Plantar fasciitis is the most common cause of heel pain. The plantar fascia camera.gif is the flat band of tissue (ligament) that connects your heel bone to your toes. It supports the arch of your foot. If you strain your plantar fascia, it gets weak, swollen, and irritated (inflamed). Then your heel or the bottom of your foot hurts when you stand or walk. Plantar fasciitis is common in middle-aged people. It also occurs in younger people who are on their feet a lot, like athletes or soldiers. It can happen in one foot or both feet.
The most frequent cause is an abnormal motion of the foot called excessive pronation. Normally, while walking or during long distance running, your foot will strike the ground on the heel, then roll forward toward your toes and inward to the arch. Your arch should only dip slightly during this motion. If it lowers too much, you have what is known as excessive pronation. For more details on pronation, please see the section on biomechanics and gait. Clinically not only those with low arches, but those with high arches can sometimes have plantar fasciitis. The mechanical structure of your feet and the manner in which the different segments of your feet are linked together and joined with your legs has a major impact on their function and on the development of mechanically caused problems. Merely having "flat feet" won't take the spring out of your step, but having badly functioning feet with poor bone alignment will adversely affect the muscles, ligaments, and tendons and can create a variety of aches and pains. Excess pronation can cause the arch of your foot to stretch excessively with each step. It can also cause too much motion in segments of the foot that should be stable as you are walking or running. This "hypermobility" may cause other bones to shift and cause other mechanically induced problems.
When plantar fasciitis occurs, the pain is typically sharp and usually unilateral (70% of cases).Heel pain worsens by bearing weight on the heel after long periods of rest. Individuals with plantar fasciitis often report their symptoms are most intense during their first steps after getting out of bed or after prolonged periods of sitting. Improvement of symptoms is usually seen with continued walking. Numbness, tingling, swelling, or radiating pain are rare but reported symptoms. If the plantar fascia continues to be overused in the setting of plantar fasciitis, the plantar fascia can rupture. Typical signs and symptoms of plantar fascia rupture include a clicking or snapping sound, significant local swelling, and acute pain in the sole of the foot.
Physical examination is the best way to determine if you have plantar fasciitis. Your doctor examines the affected area to determine if plantar fasciitis is the cause of your pain. The doctor may also examine you while you are sitting, standing, and walking. It is important to discuss your daily routine with your doctor. An occupation in which you stand for long periods of time may cause plantar fasciitis. An X-ray may reveal a heel spur. The actual heel spur is not painful. The presence of a heel spur suggests that the plantar fascia has been pulled and stretched excessively for a long period of time, sometimes months or years. If you have plantar fasciitis, you may or may not have a heel spur. Even if your plantar fasciitis becomes less bothersome, the heel spur will remain.
Non Surgical Treatment
The following recommendations are appropriate. Wear shoes with adequate arch support and cushioned heels; discard old running shoes and wear new ones; rotate work shoes daily. Avoid long periods of standing. Lose weight. Stretch the plantar fascia and warm up the lower extremity before participating in exercise. For increased flexibility, stretch the plantar fascia and the calf after exercise. Do not exercise on hard surfaces. Avoid walking barefooted on hard surfaces. Avoid high-impact sports that require a great deal of jumping (eg, aerobics and volleyball). Apply ice for 20 minutes after repetitive impact-loading activities and at the end of the day. Limit repetitive impact-loading activities such as running to every other day, and consider rest or cross-training for nonrunning days.
The most common surgical procedure for plantar fasciitis is plantar fascia release. It involves surgical removal of a part from the plantar fascia ligament which will relieve the inflammation and reduce the tension. Plantar fascia release is either an open surgery or endoscopic surgery (insertion of special surgical instruments through small incisions). While both methods are performed under local anesthesia the open procedure may take more time to recover. Other surgical procedures can be used as well but they are rarely an option. Complications of plantar fasciitis surgery are rare but they are not impossible. All types of plantar fasciitis surgery pose a risk of infection, nerve damage, and anesthesia related complications including systemic toxicity, and persistence or worsening of heel pain.
It is not always possible to prevent heel pain, but there are measures you can take to help avoid further episodes. Healthy weight. Being overweight can place excess pressure and strain on your feet, particularly on your heels. This increases the risk of damaging your feet and heels. If you are overweight, losing weight and maintaining a healthy weight by combining regular exercise with a healthy, balanced diet can be beneficial for your feet. You can calculate your body mass index (BMI) to find out whether you are a healthy weight for your height and build. To work out your BMI, divide your weight in kilograms by your height in metres squared. A BMI of less than 18.5 means that you are underweight, 18.5-24.9 means that your weight is healthy, 25-29 means that you are overweight, 30-40 means that you are obese, over 40 means that you are morbidly obese. You can also use the BMI healthy weight calculator to work out your BMI. Healthy feet. You should always wear footwear that is appropriate for your environment and day-to-day activities. Wearing high heels when you go out in the evening is unlikely to be harmful. However, wearing them all week at work may damage your feet, particularly if your job involves a lot of walking or standing. Ideally, you should wear shoes with laces and a low to moderate heel that supports and cushions your arches and heels. Avoid wearing shoes with no heels.
