Plantar fasciitis is an overuse injury affecting the connective tissue (the plantar fascia) that runs from the front of the heel bone to the ball of the foot. This dense strip of tissue helps support the longitudinal arch of the foot.
The condition starts gradually with mild pain at the heel bone. The pain usually occurs first thing in the morning, as soon as weight is applied to the feet after getting out of bed. It can also occur again when standing up after a midday lunch break. It is more likely to flare up after (not during) exercise.
You are more likely to get the condition if you are a woman, if you are overweight, or if you have a job that requires a lot of walking or standing on hard surfaces. You are also at risk if you walk or run for exercise, especially if you have tight calf muscles that limit how far you can flex your ankles. People with very flat feet or very high arches are also more prone to plantar fasciitis.
Please note: If your pain persists, seek the advice of a medical professional.
When the foot is weight-bearing, a tremendous amount of force is concentrated on the plantar fascia, similar to the string on a bow. This pressure leads to stress on the tissue that results in small tears and inflammation.
