Lumbar disc herniation develops on the basis of degenerative disc changes. Therefore, symptoms due to degenerative disc changes can be present for a significant period of time prior to the onset of disc herniation. Degenerative changes in the lumbar spine can have no obvious symptoms all the time, but they can also have the following symptoms, and these prodromal symptoms are not specific, and other diseases also have similar performance. 1. Acute lumbar pain caused by sprain. It is triggered by some slight movements. For example, bending down to pick something on the ground or bending down to wash the face suddenly has severe pain in the lower back and dare not move, and the patient often thinks that he/she has flashed or twisted his/her back. The lighter ones can barely walk carefully, while the heavier ones are bedridden. This kind of attack can gradually heal itself after bed rest or taking some pain-relieving drugs or even without treatment. 2.Recurrent episodes of low back pain This phenomenon is indicative of disc degeneration or instability of the intervertebral joints or hyperextension of the posterior joints. It has been found that 85% of the patients have an interval of 3 months-3 years between episodes of low back pain, with each episode lasting 3 days-3 weeks. In contrast, there was no low back pain during the interval. Most of them are induced by repeated posterior joint hyperextension sprains. The normal posterior joint has a certain range of motion in posterior extension, but the degenerated vertebral space and its posterior joint are already in hyperextension, so if the spine is hyperextended again, injury to the joint capsule is likely to occur. 3, chronic persistent low back pain This patient often starts with a few years of history of recurrent acute low back pain, and then gradually turns into persistent low back pain. The slightest inattention in the daily life of this patient will cause an aggravation of low back pain, so they are very careful about every kind of movement. 4.Cervical and lumbar syndrome The lower lumbar spine is most likely to cause symptoms due to disc degeneration. This degenerative change can sometimes be multi-stage affecting the entire lumbar spine, and sometimes can also affect the cervical spine will appear cervical lumbar syndrome. Usually when a patient comes to the clinic with low back pain, the degeneration of the cervical spine has not yet shown symptoms or the symptoms are mild and the patient does not mind. When cervicolumbar syndrome occurs, the patient describes that he has pain all over his body, and the pain in the neck can radiate to the occipital area, both shoulders and the upper extremities, and sometimes to the chest. Changes in the low back can cause pain in both lower extremities. This condition may be perceived by the physician as a neurological disorder or may be treated hastily by the physician due to lack of understanding.
