In clinical practice, when patients have lumbar pain and right leg pain, most of them have lesions in the lumbar spine, such as acute trauma due to chronic strain in the lumbar region, which can lead to lumbar disc herniation and nerve compression in the lumbar region, which can affect the lumbar and leg pain, accompanied by numbness and muscle weakness in the lower limbs. The patient’s lumbar spine bones, if there is hyperplasia and degeneration, can lead to lumbar spinal stenosis, which can also have this phenomenon, and can be gradually relieved after instructing the patient to carry out correct lumbar rehabilitation exercises. If the patient develops small joint instability in the lumbar spine, it can also involve the nerve roots when moving, resulting in lumbar pain and leg pain.
