The plantar fascia acts like a bowstring and supports the arch and several muscles inside the foot. When there is increased stress on the arch, microscopic tears can occur within the plantar fascia, usually at its attachment on the heel. This results in inflammation and pain with standing and walking and sometimes at rest.
You are more likely to develop plantar fasciitis if you are Active, sports that place excessive stress on the heel bone and attached tissue, especially if you have tight calf muscles or a stiff ankle from a previous ankle sprain, which limits ankle movement eg. Running, ballet dancing and aerobics. Overweight. Carrying around extra weight increases the strain and stress on your plantar fascia. Pregnant. The weight gain and swelling associated with pregnancy can cause ligaments to become more relaxed, which can lead to mechanical problems and inflammation. On your feet. Having a job that requires a lot of walking or standing on hard surfaces ie factory workers, teachers and waitresses. Flat Feet or High Foot Arches. Changes in the arch of your foot changes the shock absorption ability and can stretch and strain the plantar fascia, which then has to absorb the additional force. Middle-Aged or Older. With ageing the arch of your foot may begin to sag - putting extra stress on the plantar fascia. Wearing shoes with poor support. Weak Foot Arch Muscles. Muscle fatigue allows your plantar fascia to overstress and cause injury. Arthritis. Some types of arthritis can cause inflammation in the tendons in the bottom of your foot, which may lead to plantar fasciitis. Diabetes.

People with this condition sometimes describe the feeling as a hot, sharp sensation in the heel. You usually notice the pain first thing in the morning when you stand.

Non Surgical Treatment
A number of conservative measures can help take stress off the plantar fascia and encourage healing, including Icing, Taping the arch and bottom of the foot, Stretching, especially the calf, Avoiding walking with bare feet, especially on hard surfaces, Wearing orthotics or arch supports, Taking over-the-counter anti-inflammatories. If these methods fail, we generally try one of two things, A cortisone injection can help reduce swelling. Often a single injection will do the trick, but occasionally a second injection may be needed. Alternatively, we can try extracorporeal pulse activation therapy, or EPAT. This method uses sound waves to penetrate to the plantar fascia and stimulate the body’s healing response. We typically do one treatment a week for three weeks, with complete healing taking between nine to 12 weeks.
When more conservative methods have failed to reduce plantar fasciitis pain, your doctor may suggest extracorporeal shock wave therapy, which is used to treat chronic plantar fasciitis. Extracorporeal shock wave therapy uses sound waves to stimulate healing, but may cause bruises, numbness, tingling, swelling, and pain. When all else fails, surgery may be recommended to detach the plantar fascia from the heel bone. Few people need surgery to treat the condition.
Do not walk barefoot on hard ground, particularly while on holiday. Many cases of heel pain occur when a person protects their feet for 50 weeks of the year and then suddenly walks barefoot while on holiday. Their feet are not accustomed to the extra pressure, which causes heel pain. If you do a physical activity, such as running or another form of exercise that places additional strain on your feet, you should replace your sports shoes regularly. Most experts recommend that sports shoes should be replaced after you have done about 500 miles in them.
