Typical lumbar disc herniation usually starts with only lumbar pain, or lumbar pain can be heavier than leg pain (i.e., sciatica); when the leg pain exceeds the lumbar pain, the course of the lumbar disc herniation begins, and it can be considered a typical lumbar disc herniation. Clinical lumbar disc herniation can be lumbar pain as the initial symptom; if the discogenic pain, lumbar pain predominates for a period of time, most do not appear lumbar disc herniation course; the length of time of the antecedent symptom shows the degree of degeneration of the intervertebral discs: the occurrence of transient lumbar pain followed by the emergence of leg pain predominantly, it shows that it is a simple, “clean “clean” ruptured disc, low back pain transformed into predominantly leg pain, accompanied by low back pain exists for several months or years, indicating that the disc is highly degenerative. The persistence of pain of disc origin has a tendency to gradually subside. In lumbar disc herniation, the pain correlates with the height of lumbar forward flexion, whereas there does not seem to be a consistent correlation with sitting or lying position, especially in the acute phase. “Constipation” is also often a manifestation of lumbar disc herniation. In many patients, lateral bending of the lumbar spine in the direction opposite to the pain usually reduces the pain. Typical lumbar disc herniation includes: (1) lumbar pain: it is the clinical symptom of most patients, and is often the first symptom of the patient, most patients first have recurrent lumbar pain, followed by leg pain, some patients have lumbar pain and leg pain at the same time, and some patients only have leg pain without lumbar pain; lumbar pain is manifested as a diffuse, dull pain in lumbosacral area, which sometimes affects the buttocks; (2) sciatica: Because the vast majority of patients are L4/5 or L5/S1 disc herniation, so about 97% of patients show sciatica; typical sciatica is from the lumbosacral region to the buttocks, the posterior lateral thighs, calves, or posterior to the feet, radiating pain, patients in the abdominal pressure increases (such as coughing, sneezing, stool, etc.) or change position (such as turning over, bending over, sitting up, etc.) when the pain can be triggered.
