The difference between lumbar disc herniation and bulging is mainly reflected in three aspects, such as the stage of disease development, clinical manifestations and treatment methods. 1. Disease development stage: lumbar disc bulging usually belongs to the early lesion stage, when the local intervertebral disc will have a slight deformation, and herniation is usually a relatively serious situation in the late stage. 2. Clinical manifestations: lumbar disc bulge may appear lumbar pain symptoms, rest may be reduced or relieved, but lumbar disc herniation will often compress the surrounding nerve roots, resulting in numbness in the legs, pain and other abnormal symptoms, and lumbar pain will continue to aggravate. 3. Treatment: Lumbar bulging discs can be treated with traction to widen the intervertebral space, while lumbar herniated discs with severe symptoms require minimally invasive localized surgical treatments to remove the nucleus pulposus tissue, so that nerve compression can be relieved. There is a clear difference between a lumbar disc herniation and a bulging disc, which can be clearly diagnosed by imaging tests such as lumbar MRI or CT. It is important to maintain proper posture when sitting or standing, and if symptoms are difficult to be relieved, it is necessary to seek medical attention in a timely manner.
