What does L3 L4 L5 S 1 represent for lumbar disc herniation?

L3？ L4？ L5？ S 1 is the third lumbar vertebra? Fourth? Fifth? What about sacral protrusion? Symptoms like this are mainly due to degenerative diseases or long-term incorrect sitting posture, or twisting, flashing and hitting of the waist during labor or sports activities, as well as injuries such as excessive force and overwork when lifting heavy objects, which lead to the rupture of intervertebral disc fibers, and the emergence of nucleus pulposus tissue from the rupture opening, which stimulates or compresses the spinal nerve roots, leading to collusion between the waist and legs, that is, the waist and legs are combined with radicular sciatica and other symptoms. Because this disease is mainly caused by low back and leg pain, it is called traumatic low back pain in traditional Chinese medicine. It causes the annulus fibrosus to lose its elasticity and toughness, and the annulus fibrosus is the fibrous muscle tissue connecting spinal segments. When it loses its elasticity and toughness, it is easy to be damaged and broken like an aging rubber band. Then under some unconventional actions or loads, the fiber ring may often be torn. Thereby causing the nucleus pulposus to protrude from the annulus fibrosus and overflow. The protruding part of the nucleus pulposus has been separated from the human circulatory system, gradually calcified and turned into a new substance. Mostly inorganic. This prominent substance will cause numbness, pain, swelling, acid precipitation and other reflexes of nerve endings when it is pressed through the nerve roots near the fibrous ring. I suggest external use of Chinese medicine. Transdermal administration is mainly used to reach the focus directly. Drugs unsealed by software can soften and decompose protruding and transformed nucleus pulposus materials. Eliminate edema and improve metabolism. So that the protruding nucleus pulposus can be decomposed, softened and absorbed. And through some drugs, the annulus fibrosus and surrounding tissues are fully nourished and enter a virtuous circle. Restore the elasticity and toughness of the fiber ring.
