Leg pain in the elderly is particularly common in daily life and can be caused by a number of reasons, which can be divided into the following: 1. The pain is induced by a lack of calcium and osteoporosis in the body. 2. Trauma, such as a fall or sprain, causes local pain or swelling. 3. It may also be due to a herniated lumbar disc that compresses the nerves in the lower limbs and induces leg pain. 4. varicose veins, inducing the patient to develop leg soreness. For elderly people with leg pain, they can take Nimesulide, ibuprofen, diclofenac sodium drugs orally for anti-inflammatory and analgesic purposes, or they can apply heat to the painful area to relieve it.
