Lumbar protrusion is more serious than lumbar curvature straightening. Lumbar protrusion is a herniated lumbar disc, and straightened lumbar curvature may develop into a herniated lumbar disc if not corrected in time. Prolonged sitting or bending can lead to straightening of the physiological curvature of the lumbar spine, and the muscles of the lumbar back will experience pain, and it is simple localized soreness or distension, which does not radiate to the lower limbs, and this situation usually causes inflammation of the lumbar back fascia and muscle strain, which can be cured by giving medication. If the physiological curvature of the lumbar spine is straightened and the pain radiates to the lower limbs, most of them are considered to be lumbar disc herniation, which is mainly caused by the herniated disc compressing the nerves. In this case, medication is needed, and surgery is usually needed if the systematic medication is ineffective or ineffective. Lumbar spine physiological curvature straightening and lumbar protrusion may also have other causes, it is recommended to go to the hospital in a timely manner to consult the doctor, after diagnosis to give targeted treatment or treatment.
