The painful condition of the blood vessels in the feet is caused by the formation of thrombus in the blood vessels or the narrowing or occlusion of the arteries, which can cause pain in the feet. A thrombosis in the blood vessels of the foot can cause superficial thrombophlebitis, which results in redness, swelling, pain, and increased skin temperature, as well as the ability to palpate a hard stripe with very pronounced tenderness. If the arterial vessels are narrowed or occluded, resulting in ischemia and hypoxia in the distal tissues, because of insufficient blood supply to the arteries, it will lead to metabolic disorders in the body, not being able to replenish sufficient oxygen and nutrients, and the tissues of the patient’s feet are in a nutritional metabolic disorder, which will cause pain at this time. So this situation must go to the hospital, for timely treatment.
