The main systemic symptoms of lumbar disc herniation mainly include low back pain, radiating pain, numbness and abnormal sensation in the lower limbs, intermittent claudication, change of spinal posture and muscle paralysis. The specific systemic symptoms of lumbar disc herniation have the following aspects, let’s take a look. 1.Lumbar back pain: this kind of pain appears before the leg pain, can also appear at the same time. The pain is mainly in the lower lumbar or lumbosacral area, and the cause of the pain is mainly due to the stimulation of the outer layer of the annulus fibrosus and the sinusoidal nerve fibers in the posterior longitudinal ligament after the herniation of the intervertebral disc. The pain site is deeper, difficult to locate, usually dull, stabbing or radiating pain. 2, lower extremity radiating pain: due to the lumbar intervertebral disc herniation occurs in the lumbar 4, 5 and lumbar 5 sacral 1 intervertebral space, and the sciatic nerve is precisely from the lumbar 4, 5 and sacral 1-3 nerve roots, so the lumbar intervertebral disc herniation patients have sciatica or buttocks to begin with, and then gradually radiate to the back of the thighs, calves, dorsal feet and soles of the outer side of the feet and toes. The central type of herniation often causes bilateral sciatica. When coughing, sneezing and defecation and other intra-abdominal pressure increases, the radiating pain of the lower limbs is aggravated. 3, numbness and sensory abnormalities: lumbar intervertebral disc herniation can cause localized compression and pulling compression in the nerve root contact area, causing ischemia and hypoxia due to compression of fibers and blood vessels in the nerve root itself, so pain, numbness and other abnormal sensations occur in the innervated area of the affected nerve root. 4, intermittent claudication: due to the herniated disc compressing the nerve root, causing congestion, edema and other inflammatory reactions and ischemia of the nerve root, when walking, the blocked vertebral venous plexus in the vertebral canal is congested, which aggravates the congestion of the nerve root and the expansion of the spinal cord blood vessels, and at the same time aggravates the compression of the nerve root and the emergence of intermittent claudication and pain. 5, spinal posture changes: about 90% of patients have different degrees of functional scoliosis after lumbar disc herniation, most of which are convex to the affected side, and a few are convex to the healthy side, depending on the relationship between the protrusion and the nerve root. Scoliosis relaxes the nerve root and reduces pain. If the herniation is anterolateral to the nerve root, the spine projects to the affected side. If the herniation is medial to the nerve root, the spine is convex to the healthy side. Side bending is a protective measure to reduce the compression of the protrusion on the nerve root. 6, muscle paralysis: lumbar intervertebral disc herniation compression of nerve roots for a long time, can cause nerve root ischemia and hypoxia degeneration and nerve paralysis, muscle paralysis. Lumbar 4, 5 intervertebral disc herniation can cause lumbar 5 nerve root paralysis caused by tibialis anterior, fibularis longus shortus, extensor digitorum longus and extensor digitorum paralyzed. Lumbar 5 sacral 1 disc herniation, sacral 1 nerve root involvement paralysis and the calf triceps paralysis. Lumbar disc herniation is common in young adults, especially in manual laborers or prolonged sitting and standing workers, and there is no significant difference in the incidence of men and women. When the above symptoms occur, lumbar disc herniation can be suspected, and should be early medical examination.
