A herniated disc is the result of degeneration and injury to the intervertebral disc, and even if there is nerve compression on the imaging, a significant proportion of people have no symptoms; 20% of normal people have a herniated disc (MRI shows a herniated disc), and this change is degeneration, representing the aging stage of human growth and development, and is not a disease, and certainly does not require treatment. If the herniated disc irritates or compresses the nerves, resulting in back and leg pain, numbness and weakness, we call it a herniated disc, which is a disease and needs to be “treated”. The good thing is that more than 70% of patients with lumbar disc herniation are self-limiting, and generally the symptoms will disappear on their own within 3 weeks to 3 months.
