Lumbar disc herniation develops on the basis of degenerative changes in the intervertebral discs. Therefore, before the occurrence of lumbar disc herniation, a series of antecedent symptoms may arise 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 mistaken by patients as “flashing back” and not paid attention to. 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, their posterior joints are already in hyperextension because of the degenerated vertebral space, so the spine is prone to joint capsule injury if hyperextension is made again, which induces the occurrence of lumbar disc herniation. 3, chronic low back pain: some patients after several acute low back pain episodes of pain, gradually formed a continuous chronic low back pain. This kind of low back pain is often aggravated after coughing and bowel exertion. All of the above symptoms herald the potential possibility of lumbar disc herniation, but none of them are also specific, and patients with such symptoms are expected to treat them correctly.
