The discomfort in the hip axis after walking is due to the frequent muscle contractions and hip flexion and extension activities, which can lead to strain on the surrounding muscles and soft tissues and local formation of sterile inflammatory lesions, and the metabolites can stimulate the peripheral nerves, resulting in soreness and discomfort. Usually there is also a combination of cold, because the blood circulation is faster when walking a lot, and the inflammatory metabolites produced by the strain can be metabolized effectively. However, when resting, the blood circulation slows down and local sweat evaporates, resulting in local cold, which leads to further accumulation of inflammatory metabolites and more stimulation of peripheral nerves, leading to further discomfort and tension in the muscles, which also slows down blood circulation and leads to poor muscle nutrition after the blood supply to the small arteries decreases. The decrease in blood supply to the small arteries leads to a poorer nutritional status of the muscles, and the constriction of the veins leads to a further increase in inflammatory metabolites produced by the blood circulation, leading to an increase in symptoms.
