A straightened lumbar spine suggests degenerative changes in the area of the lumbar spine, which may or may not cause significant symptoms of back pain. If the lumbar spine is only checked to be straightened and there is no obvious pain or discomfort, follow-up observation is fine. If the lumbar spine is straightened, accompanied by pain and discomfort, you can give local creams, such as pain-relieving creams, and also take oral painkillers, such as aminoglutethimide. The straightening of the waist suggests degeneration of the lumbar spine, so pay attention to personal posture and avoid long-term sedentary, prolonged standing, repeated bending and heavy physical labor to help delay the continued degeneration of the waist. It is important to observe whether there are other combined phenomena, such as the presence of radiating pain in the lower limbs. Sometimes the lumbar straightening is accompanied by lumbar disc herniation, which can cause back pain and radiating pain in the lower extremities, which requires further examination, such as magnetic resonance imaging of the lumbar spine.
