Lumbar disc herniation develops on the basis of degenerative changes in the intervertebral discs. Therefore, before the occurrence of lumbar disc herniation, there may be a series of precursor symptoms due to degenerative changes of the intervertebral disc, which are not specific and therefore not unique to the lumbar intervertebral disc. 1, acute lumbago: The lumbago referred to here is different from the lumbago caused by inadvertent sprain of the waist when engaging in sports or heavy physical labor. It is mostly triggered by some slight movements, so it is often mistakenly thought by patients as “flashing back” and not taken seriously. 2. Recurrent low back pain: In case of lumbar disc degeneration and intervertebral joint instability or posterior joint hyperextension, patients may have recurrent low back pain. The interval between each attack varies from several days to several months. In this kind of patients, because their degenerated vertebral space makes their posterior joints are already in hyperextension, so if the spine is hyperextended again, joint capsule injury is likely to occur, and the occurrence of lumbar disc herniation is triggered. 3, chronic low back pain: some patients after several episodes of acute low back pain pain pain, gradually formed a continuous chronic low back pain. This kind of low back pain is often aggravated after coughing and bowel exertion. The above symptoms all indicate the potential possibility of lumbar disc herniation, but none of them are specific, so we hope that patients with such symptoms can treat them correctly.
