CT showed lumbar disc herniation of 7 mm, and MRI showed lumbar 5- sacrum 1 disc degeneration protruding to the lower right, corresponding to spinal canal stenosis at the intervertebral disc level.

According to the description, it should be serious, and the intervertebral disc is herniated. According to your description, you can consider surgery.

It is best to combine physical signs. If low back pain is accompanied by severe pain in the right lower limb, you can operate if you can't rest in bed. Conservative treatment such as traction of disc herniation has little effect.

If the nucleus pulposus is removed, that is, the protruding part is removed, there is a certain recurrence probability, and the total cost is about 2 weeks.

Internal fixation and bone graft fusion can completely remove the diseased intervertebral disc and replace it with artificial implant. After the operation, this segment will not recur, but it may lead to degeneration in adjacent stages, and new symptoms may appear after a few years. This will take about 4-5w.
