What is plantar fasciitis?

Mr Mushtaq, plantar fasciitis is a commonly used term. What is plantar fasciitis? Plantar fasciitis is an inflammation of the plantar fascia which is the structure underneath the heel or underneath the foot. It originates from the heel and extends all the way to the big toe. However, most of the pain will originate at the source which is near the heel. Commonly people associate it with a plantar spur or a heel spur, which they think actually is the cause of the pain, it's not the cause of the pain, the pain is originating from the actual fascia and the spur is associated with that tightness.
