Lumbar 4/5, Lumbar 5/Sacral 1 bulging disc is a bulging disc in the lumbar 4/5, lumbar 5/sacral 1 vertebrae due to a partial but not complete fracture of the annulus fibrosus, which does not enter the spinal canal, and does not normally compress the nerve root, causing mild clinical symptoms.
A bulging disc is a disc in which the nucleus pulposus does not break through the surrounding annulus fibrosus, and it is the mildest type of herniated disc. A bulging disc does not compress the surrounding nerves and does not produce significant clinical symptoms.
If the nucleus pulposus breaks through the surrounding annulus fibrosus, it is called a herniated disc, and a herniated disc can lead to peripheral nerve compression, causing clinical symptoms such as low back pain, numbness, or weakness. If the lumbar disc herniation is more serious, it will lead to disc protrusion, free disc, and disc prolapse, which is the most serious type of disc herniation.
In case of lumbar 4|5 lumbar 5|sacral 1 disc bulge, it is recommended to go to the hospital in time for regular treatment.
