Plantar fasciitis is the most common cause of chronic inferior heel pain (see photo). There are many risk factors that may attribute to its development. It is believed to be caused by acute or chronic injury to the origin of the plantar fascia from cumulative overload stress.
The pain can last from months to even years and is typically present upon weight bearing. It is a throbbing, searing, or piercing pain especially with the first few steps in the morning or periods after inactivity.
