The basic cause of walking pain caused by heel bone spurs is the long-term chronic stimulation of the soft tissues of the foot by the bone spurs, so that the local production of chronic aseptic inflammation, aseptic inflammation and its metabolites stimulate the nerve endings of the foot tissues, resulting in pain and discomfort. If a person is walking, the bone spur will inevitably rub against the surrounding muscles, tendon membrane and other soft tissues, resulting in different degrees of tissue damage. These injuries include local hemorrhage, edema, exudation, fibrosis of the tissue, infiltration of inflammatory cells (such as lymphocytes), accumulation of metabolites in the local tissues, etc. All of these injuries and reactions stimulate the sensory nerves and make people feel pain. In addition, the pressure of the bone spur on the skin and soft tissues of the bottom of the foot when walking, as well as blood stasis and increased pressure in the heel bone, are also a cause of pain.
