L2I3I4I5 bulging disc refers to lumbar 2I3I4I5 bulging disc. If there is no compression to the nerve root or spinal cord, and no corresponding symptoms, it can be considered not very serious, but if there is compression and the corresponding symptoms are more serious, it is recommended to consult a doctor in time to clarify the specific situation. 1. Herniated lumbar discs can be broadly categorized into three types according to their degree: bulging discs, herniated lumbar discs and prolapsed lumbar discs. 2. The lightest degree of lumbar disc bulging. A lumbar bulging disc is a slight degeneration of the intervertebral disc, in which the nucleus pulposus loses its moisture and bulges out to the surrounding area, which may not cause symptoms in some people and does not require treatment. 3. A small number of patients with bulging discs may experience low back pain, numbness in the lower extremities, and radiating pain. If the pain or numbness has affected normal work and life, minimally invasive surgery can be considered. Generally speaking, bulging discs are not serious, and the same applies to multi-segment ones, which can be treated conservatively by paying attention to rest and strengthening exercises.
