The causes of tired and sore feet include excessive exercise, overwork, and prolonged standing.
1. Exercise excess: such as running for a long time, playing basketball, etc., resulting in excessive generation of lactic acid in the body can not be discharged in a timely manner, thus causing lower limb soreness, fatigue and other symptoms.
2. Excessive exertion: such as prolonged physical labor, resulting in foot tendon strain, decreased muscle tone, coupled with the accumulation of lactic acid generated by the local metabolism, resulting in lower extremity and foot fatigue, soreness and other symptoms.
3. Standing for a long time: if you stand for too long, due to gravity, it may cause obstruction of blood reflux in the lower limbs and feet, which can not return to the heart in time, and fresh blood can not be circulated here, thus causing ischemia and hypoxia of the muscle tissues of the lower limbs and causing symptoms such as soreness and fatigue.
In addition to the above reasons, lower extremity vascular sclerosis can also cause the above symptoms. If the above symptoms do not improve, or are accompanied by other uncomfortable symptoms, you should go to the hospital in a timely manner to clarify the cause and give targeted treatment.
