The plantar fascia is a tough and flexible band of tissue that runs under the sole of the foot. It connects the heel bone with the bones of the foot, and acts as a kind of shock absorber to the foot. Sudden damage, or damage that occurs over many months or years, can cause tiny tears (microtears) to develop inside the tissue of the plantar fascia. This can cause the plantar fascia to thicken, resulting in heel pain. The surrounding tissue and the heel bone can also sometimes become inflamed.
Causes can be by one or a combination of foot activity overloads. Jogging, climbing, or walking for extended periods puts too much stress on the plantar fascia. But even routine, non-athletic activities such as moving heavy furniture can set off pain. Some kinds of arthritis are also attributed to plantar fasciitis. Certain arthritic conditions cause the tendons of the heel to swell. Diabetes is also a culprit- there is still no explanation why, but studies have repeatedly shown that diabetics are more prone to developing plantar fasciitis. In some cases, plantar fasciitis is triggered by shoes of poor quality or shoes that do not fit. Those with thin soles, no arch support, and no shock-absorbing properties, for example, do not five feet enough protection. Shoes that are too tight and those with very high heels can also cause the Achilles tendon to tighten, straining the tissue surrounding the heels.
Symptoms of plantar fasciitis can occur suddenly or gradually. When they occur suddenly, there is usually intense heel pain on taking the first morning steps, known as first-step pain. This heel pain will often subside as you begin to walk around, but it may return in the late afternoon or evening. When symptoms occur gradually, a more long-lasting form of heel pain will cause you to shorten your stride while running or walking. You also may shift your weight toward the front of the foot, away from the heel.
Diagnosis of plantar fasciitis is based on a medical history, the nature of symptoms, and the presence of localised tenderness in the heel. X-rays may be recommended to rule out other causes for the symptoms, such as bone fracture and to check for evidence of heel spurs. Blood tests may also be recommended.
Non Surgical Treatment
First check your shoes for too much midfoot flexibility and check your training for changes. A detailed evaluation of changes in your training is necessary. You should start with what is called "relative rest" which means a decrease in workout intensity, duration of session and decrease in the number of sessions per week. The most important part of self treatment for this condition is being sure that your shoes offer sufficient stability and are optimal in controlling the forces that contribute to plantar fasciitis and heel spurs. Check your running shoes to make sure that they are not excessively worn. They should bend only at the ball of the foot, where your toes attach to the foot. This is vital! 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 should also be doing gentle calf stretching exercises. This will reduce stress on the plantar fascia in two ways. The first manner in which a relaxation of the tension in the calf muscles can help heel pain is that it will reduce the direct pull backwards on the heel bone (calcaneus). The second reason is a little bit more complicated, but essentially it is that a tight achilles tendon and calf muscles causes the rearfoot to move in a manner that causes over pronation as your leg and body move forward over your foot. So go ahead and gently stretch the calf muscle by doing the runner's wall leaning stretch. To strengthen the muscles in your arch toe curls or "doming" can be done. 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.
The majority of patients, about 90%, will respond to appropriate non-operative treatment measures over a period of 3-6 months. Surgery is a treatment option for patients with persistent symptoms, but is NOT recommended unless a patient has failed a minimum of 6-9 months of appropriate non-operative treatment. There are a number of reasons why surgery is not immediately entertained including. Non-operative treatment when performed appropriately has a high rate of success. Recovery from any foot surgery often takes longer than patients expect. Complications following this type of surgery can and DO occur! The surgery often does not fully address the underlying reason why the condition occurred therefore the surgery may not be completely effective. Prior to surgical intervention, it is important that the treating physician ensure that the correct diagnosis has been made. This seems self-evident, but there are other potential causes of heel pain. Surgical intervention may include extracorporeal shock wave therapy or endoscopic or open partial plantar fasciectomy.
While it's typical to experience pain in just one foot, massage and stretch both feet. Do it first thing in the morning, and three times during the day. Achilles Tendon Stretch. Stand with your affected foot behind your healthy one. Point the toes of the back foot toward the heel of the front foot, and lean into a wall. Bend the front knee and keep the back knee straight, heel firmly planted on the floor. Hold for a count of 10. Plantar Fascia Stretch. Sit down, and place the affected foot across your knee. Using the hand on your affected side, pull your toes back toward your shin until you feel a stretch in your arch. Run your thumb along your foot--you should feel tension. Hold for a count of 10.
