I. Is the back and leg pain a herniated disc compressing a nerve? If a herniated disc is compressing a nerve, how can the following be explained: 1. Patients with a herniated disc who have undergone CT or MRI within six months after surgery have been found to have no change in the site of the herniation. 2. Why a patient with a bulging disc can also have the same symptoms of back and leg pain as a patient with a herniated disc. 3. With our CT-guided drug therapy, the patient’s back and leg pain can disappear, but the herniation does not change on CT and MRI. 4.Some normal people have no symptoms of low back and leg pain, but there are manifestations of herniated discs on CT and other imaging. Second, the more expensive the treatment cost, the better the treatment effect? Third, does the intervertebral disc itself have function? Fourth, does the intervertebral disc have a self-repair function? V. Do patients only care about the herniated discs when treating them? Is the treatment of lumbar herniation only the responsibility of the doctor? VII. Can a herniated disc be pushed back when pushing? VIII. Do patients with lumbar synostosis exercise more when they have back and leg pain? IX. Is the decision of needing treatment based on CT and MR imaging alone? X. Use multiple interventions at the same time for one disc?
