I posted here for the first time a while ago, and couldn't locate my original thread, so I'm posting a new question. I've had chronic low back pain for approx. 3 years, and for the last 10 months or so, have started having pain going down both legs and into my calves. I recently had an EMG/NCV study done, and the neuro diagnosed me with L5 radiculopathy. She has given me a referral to a pain management center for treatment. Up till now, I've had 3 MRI's and have two small bulges (~2-3mm) at L4/L5, and at L5/S1. I've had a total of 5 ESI's over the last 3 years, with no relief at all. I was planning on having a discogram performed, to confirm what the source of my low back pain was.
Here's the twist. Up till now, all of my MRI's have been lumbar spine MRI's. I have felt some tightness/pain in the middle of my spine, I guess that would be the thoracic area. I've never had an MRI of that area, nor of my sacrum; just the lumbar has been looked at. Should I have another MRI for my entire spine, just to make sure there's nothing else going on that I don't know about? Or should I just proceed with having a discogram of the lumbar area? My line of thinking was it would be critical to know if there is anything else wrong with my spine prior to having the discogram procedure done. If other trouble spots were found, those could also be included in the discogram procedure.
I welcome any thoughts/advice on this. I know a good number of you have already had to unfortunately go through this. Thanks!
