When leg cramps occur in the elderly, the cause should be clearly identified first, and then treated accordingly. If it is caused by head disease, such as nerve destruction in the brain caused by cerebral infarction, it is necessary to actively apply medications to activate the blood, such as thrombosis injection, and also apply anticoagulant medications to treat aspirin enteric tablets, and actively apply nutritional brain cell medications such as cytarabine sodium capsules. If the leg cramps are caused by lumbar disc herniation or lumbar spinal stenosis, the elderly should be treated with peripheral nerve nourishing drugs such as methylcobalamin capsules and methylcobalamin injection. At the same time, it is necessary to keep the patient warm and apply dehydration to reduce the pressure in the spinal canal and the swelling of the nerve roots, such as Mai Zhi Ling tablets, mannitol injection or sodium heptaerythrone for injection. If the leg cramps are caused by calcium deficiency, the elderly should actively supplement calcium carbonate D3 and calcium gluconate oral solution, and if necessary, intravenous calcium gluconate injection.
