Plantar fasciitis is a painful and limited movement caused by a sterile inflammation of the plantar fascia. The plantar fascia is a layer of flexible soft tissue that is attached to the underside of the arch and is used to protect the arch of the foot. When the human body degenerates and after long-term weight-bearing walking, sports or labor, the plantar fascia will be repeatedly stimulated, causing degeneration and inflammation, which may lead to pain in the medial heel and the formation of localized bone spurs, the most typical symptom of which is the obvious stabbing pain in the heel when waking up early in the morning and walking on the ground at the beginning, but the pain will be relieved after a few more steps or continued activities, but However, as the walking time increases, the pain increases again.
