A bulging disc compressing the dural sac is usually a very mild lesion, and if there is no discomfort, then treatment is usually not necessary and regular review is sufficient. 1. Lumbar disc lesions are bulging, herniated and prolapsed in descending order of severity and can occur anywhere in the spine, but they are most common in the cervical and lumbar spine. This is because the lumbar and cervical regions bear the most weight and are the areas of greatest spinal mobility. 2. If there is a bulging disc compressing the dural sac, if only the MRI or CT reports that the bulging disc is compressing the dural sac without symptoms such as low back or leg pain, there is usually no need to worry, and a regular review in the hospital is sufficient. Disc lesions may have no symptoms and may go undetected for months or even years. Disc degeneration is a normal part of the aging process, and many people have disc pathology without pain and without it affecting their quality of life. A bulging disc compressing the dural sac without any symptoms can simply be observed on a regular basis, but when manifestations such as low back and leg pain occur, it is recommended to visit a hospital promptly.
