Bone spurs in the heel usually have two reasons: first, the Achilles tendon and the back side of the heel bone have attachment points, due to long-term walking sports, excessive activity, cold, resulting in Achilles tendon and bone attachment points of the position of the strain or strain, and in the case of cold, the formation of aseptic inflammatory lesions. After a long time, the calcium salts inside the inflammatory lesions are gradually deposited, forming calcification and bone spurs, calcification and bone are stimulation of the surrounding soft tissues, the formation of inflammatory lesions stimulate the nerves will appear obvious pain. Second, due to the heel bone plantar, that is, the lowest position of the heel bone, due to long-term walking or wearing shoes is not soft enough, to the surrounding tissues produce stimulation, skin or subcutaneous tissue abrasion, after a long time will also form inflammatory foci, calcium salt deposition will also form bone spurs.
