When you get up in the morning, the pain and stiffness in the lower back may be due to the following reasons: First, it may be a mattress or bed board problem, if the mattress is too soft, or the bed board is too hard, it is possible that when you sleep, the muscles of the lower back must exert themselves for a long time to maintain the posture of the lumbar spine, which leads to strain pain. After you get up and move around a little or press softly locally, then the symptoms will soon improve. Second, it may be the cause of the lumbar muscles, such as lumbar strain or the third lumbar transverse process syndrome, where the third lumbar transverse process syndrome, the obvious pressure point is in the third lumbar transverse process, and lumbar strain, usually the pressure pain is bilateral lumbar muscle, widespread pressure pain is the main. Thirdly, it may be a lumbar disc herniation, usually the painful area is in the middle lumbar intervertebral space, which may also lead to nerve pulling pain in the hip and lower limbs. If you want to diagnose lumbar disc herniation, you have to go to the hospital to check the lumbar spine CT or MRI to be able to confirm the diagnosis
