The plantar fascia is a band of connective tissue on the bottom of the foot that helps form the arch of the foot. Acute injury or cumulative trauma to the plantar fascia can be a cause of inflammation and heel pain. This is called plantar fasciitis.
Plantar fasciitis occurs when the ligament in your foot arch is strained repeatedly, which causes tiny tears and significant pain. There are several possible causes for this condition. Excessive pronation, or overpronation, which happens when your feet roll excessively inward as you walk. Flat feet or high arches. Walking, standing, or running for long periods of time, particularly on hard surfaces (a common problem for athletes). Excess weight, such as overweight or obesity. Shoes that are worn out or don’t fit well. Tight calf muscles or Achilles tendons.
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.
To diagnose plantar fasciitis, your doctor will physically examine your foot by testing your reflexes, balance, coordination, muscle strength, and muscle tone. Your doctor may also advise a magnetic resonance imaging (MRI) or X-ray to rule out other others sources of your pain, such as a pinched nerve, stress fracture, or bone spur.
Non Surgical Treatment
In the early stages of plantar fasciitis resting the foot may ease the pain. Medication to reduce inflammation should help but should only be used short term. Strapping may temporarily reduce the pain. All of the above therapies are only temporary measures and the pain is likely to reoccur if the cause of the abnormal pressure which has triggered the plantar fasciitis has not been identified. In order to establish the cause of the plantar fasciitis a biomechanical assessment may be required.
In cases that do not respond to any conservative treatment, surgical release of the plantar fascia may be considered. Plantar fasciotomy may be performed using open, endoscopic or radiofrequency lesioning techniques. Overall, the success rate of surgical release is 70 to 90 percent in patients with plantar fasciitis. Potential risk factors include flattening of the longitudinal arch and heel hypoesthesia as well as the potential complications associated with rupture of the plantar fascia and complications related to anesthesia.
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.
