If the problem of cold occurs, you can add clothes to the elderly and pay attention to the warmth of the legs, and you can also do moxibustion or physical therapy to relieve muscle spasms. If the cramps are low in calcium, you can take the elderly to the hospital to check the blood calcium appropriately and replenish calcium and osteotriol appropriately, which are good for the cramps of the elderly. If the nervous cramps are more serious, you can check the CT of the head to determine if the cramps are caused by the head, which is very helpful for the diagnosis and treatment of cramps in the elderly.
