Thanks for the responses. The issue is one that an MRI does not give a clear picture.
My MRI notes:
L5/S1 disk desiccated, slight loss of disk space. Posterior and to the right annular tear but no disk protrusion, neural foramina patent.
L3/L4 Broad Based central protrusion (4mm) which mildly effaces the thecal sac, neural foramina patent.
All other levels are fine.
This MRI could be anyone, with no problems. I have left sciatica which at times feels like L5/S1 and other times like L4/L5. I have no back pain, which is usually the primary symtom for DDD. However with a herniation it is likely to have sciatica with no back pain.
Othropedic surgeon feels it could be from the central protrusion at L3/L4 effecting the nerve roots going to my left side in the spinal canal. Injection shoud be given at L4/L5.
Pain DR. feels L5/S1 tear is the problem. Althought the tear is to the right the leak disc could be working it's way to the left.
I can't imagine a discogram to indicate where to give a steroid injection.
So I'm not sure what I should push for. Any opinions are appreciated.
