Lumbar disc herniation is a lumbar spine disease, engaged in copywriting work and other sedentary people as well as people engaged in manual labor are more likely to suffer from lumbar disc herniation, so what kind of symptoms will patients with lumbar disc herniation have? It mainly has the following symptoms. Spinal deformation: When people have a lumbar disc herniation, then there will be different degrees of functional scoliosis, convex to the affected side more, convex to the healthy side less, the main death is to see the relationship between the herniation and the nerve root. Lateral bending relaxes the nerve root and reduces pain. If the protrusion is on the anterolateral side of the nerve root, the spine will be convex to the affected side; if the protrusion is on the medial side of the nerve root, the spine will be convex to the healthy side. Lateral bending is actually a protection to reduce the compression of the nerve root by the protrusion. Intermittent claudication: Patients with lumbar disc herniation may have heavy objects compressing the nerve roots, causing inflammatory reactions and ischemia such as congestion and edema of the nerve roots. When walking, the congestion of the obstructed vertebral vein plexus in the spinal canal aggravates the degree of congestion of the nerve roots and the expansion of spinal blood vessels, which also aggravates the compression of the nerve roots and results in intermittent claudication and pain. Low back pain: This pain appears before leg pain or can occur at the same time. The pain is mainly in the lower back or lumbosacral region, and is caused by a herniated disc that stimulates the sinus nerve fibers in the outer layer of the annulus fibrosus and the posterior longitudinal ligament. The pain is deep and difficult to localize, and is usually dull, stabbing or radiating. Muscle paralysis: If the herniated part of the lumbar disc after herniation compresses the nerve root for a longer period of time, it can cause nerve paralysis and muscle paralysis due to ischemic and hypoxic degeneration of the nerve root. A herniated lumbar disc can cause paralysis of the anterior tibial muscle, peroneal long and short muscles, extensor hallucis longus and extensor digitorum longus muscles due to paralysis of the lumbar nerve roots. After a lumbar disc herniation, paralysis of the nerve roots is involved and paralysis of the triceps calf muscle occurs. Body numbness and abnormal sensation: After a lumbar disc herniation, it can cause localized compression and traction compression in the nerve root contact area, causing ischemia and hypoxia due to pressure on the fibers and blood vessels of the nerve root itself, so abnormal sensations such as pain and numbness appear in the area innervated by the affected nerve root. Lumbar disc herniation may involve the lumbar 5 nerve root and cause abnormal sensory numbness in the posterior thigh, lateral calf, lateral dorsal foot and dorsal bunion. A lumbar disc herniation can involve abnormal skin sensation on the dorsal side. If the herniated disc compresses or stimulates the paravertebral sympathetic nerve fibers, it can reflexively cause the lower extremity blood vessel wall to contract and result in coldness, chilliness, and weakening of the dorsal foot artery. Radiation pain in the lower extremities of the body: Patients with lumbar disc herniation mostly have sciatica, mostly starting from the buttocks and gradually radiating to the posterior lateral thigh, lateral calf, dorsum of the foot and lateral plantar and toe of the foot. The central type of herniation often causes bilateral sciatica. The transmission-like lower extremity radiating pain is aggravated by increased intra-abdominal pressure such as coughing, sneezing, and urination and defecation. Lower extremity pain is one of the main symptoms of lumbar disc herniation.
