Most of the back pain in the elderly is due to lumbar disc herniation or lumbar spinal stenosis, which often requires conservative treatment: 1. physical therapy for the back, microwave physical therapy or far-infrared physical therapy. 2. external fixation of the lumbar girth, which can increase the strength of the back and reduce the pain of the back. 3. oral medication, oral pain medication, such as celecoxib, meloxicam, oral Chinese medicine, such as lumbar pain capsules, astragalus pellets, and calcium supplementation. 4. If the effect of conservative treatment does not improve or continues to worsen, consider surgery.
