Leg pain after standing for too long may be caused by muscle fatigue, meniscus injury, varicose veins and degenerative osteoarthritis, etc. Corresponding treatments can be chosen according to the cause of the disease, such as general treatment, medication and so on. 1. Muscle injury: Standing for too long may cause the leg muscles to accumulate too much lactic acid, which cannot be metabolized in time, thus leading to pain. It can be relieved by rest, hot compress, massage, etc., without much worry. 2. Meniscus injury: Degeneration, trauma and other factors may lead to meniscus injury, which will cause pain, popping, limited movement and other symptoms. Meniscus injury can be treated conservatively and surgically, such as reducing activities, plaster immobilization treatment, meniscoplasty and meniscus suture. 3. Varicose veins of the lower limbs: prolonged standing will cause varicose veins of the lower limbs, which will cause pain, soreness and swelling of the affected limbs.
