I am 33. I had previous surgery on 2 lumbar vertebrea in the lower back 12 years ago. Before the surgery the pain was shooting down the right side from lower back to right foot. Now 12 years later I have the same chronic pain down the left side. Been to doctor and sent for physio and scans. Findings from scan is a right sided laminectomy defect at the L5 level. The L5-S1 intervertebral disc degenerate with gas present within degenerate disc and associated with small righ tsided posterolateral herniation of the disc with the herniating disc abutting the right S1 nerve root which seems to be displaced posteriorly, however, fat, is present posterior to the thecal sac at thos level adjacent to the laminectomy defect. I am 75kg and 6ft 2in and do exercise. Can you help.
