If there is a sudden lightning pain in the lumbar area, it is caused by abnormal friction in the small joints of the lumbar area. For example, if the lumbar area rotates or suddenly gets up after sitting for a long time, it will cause abnormal friction in the cartilage of the small joints of the lumbar area, which will cause obvious pain in the lumbar area, but the symptoms will disappear after the pain. Second, see the lumbar muscle, fascia stretch injury, after a long period of inactivity, will lead to the lumbar muscle, fascia in a relaxed state, and suddenly get up and move, will lead to the lumbar muscle, fascia excessive force pull a little, will cause obvious lightning pain. If the strain injury is not heavy, there will be no obvious symptoms of lumbar pain after the pain. Third, in patients with herniated lumbar discs, if the herniated discs do not significantly compress the nerve roots, but only cause pressure on the nerves when the body is in a certain posture, there will also be sudden pressure on the nerve roots when the lumbar region changes posture, causing a weakened nerve root conduction, which will also lead to a sudden lightning pain in the lumbar region.
