Walking too much causes pain in the ankle, mainly for the following reasons: First, walking too much leads to continuous tension and fatigue in the tendons, ligaments and muscles around the ankle joint, resulting in strain and injury, forming sterile inflammatory lesions, and the inflammatory metabolites will stimulate the peripheral nerves around it, producing a significant pain sensation. Usually, after activity, the ankle joint will be cold, once cold will lead to slowed blood circulation and accumulation of inflammatory metabolites, leading to further aggravation of inflammatory edema and further aggravation of pain. Second, degeneration of the ankle joint, such as excessive activity, strenuous exercise and trauma, will form degeneration of the articular cartilage, after the gradual thinning of the articular cartilage, will lead to friction between the bone and the bone, after a long time, will lead to the formation of osteophytes or calcification, these growths and calcification stimulate the surrounding soft tissue, will lead to ankle pain, usually after walking more The friction of the ankle joint gradually increases, which will lead to a significant increase in the stimulation of the surrounding tissues by the hyperplasia and calcification, resulting in pain.
