Got my MRI(s) done last week.
The results:
Occasional bulging discs (doc said which ones when she called me but I forget which ones); some mild stenosis around L4-L5 and L5-S1 (I think), though supposedly not enough to explain the symptoms (numbness / tingling) I’m having. Overall a number of places with arthritic changes. No obvious evidence of a traumatic injury (I had a nasty fall about 10 years ago, and saw a bruise right on my spine the next day, which was a bit frightening). And some of the supporting ligaments overall show some shredding (I think that was the word) which is most likely “normal” wear and tear.
So, the arthritic changes are probably what is causing the night-time back pain (my brother has complained of the same thing). Which is good and bad: good in that nothing needs to be done, bad in that nothing really CAN be done. Oh well.
No need to rush to see a spinal specialist at this point, though I presume if the symptoms get worse we could go with injections (steroids?).
The immediate plan is a course of PT to work on strengthening the supporting muscles (plus losing a bit of weight).
A couple of funnies about the MRI. I asked for a script for some happy juice - I’m slightly claustrophobic, and I know those tubes are narrow, and I see no reason to put myself in a position where I might panic. I’d never had Valium before; doc gave me a scrip for 2 5 mg tablets, to take one a bit before, then if I needed it take the second one. So, 10 minutes before, I wasn’t feeling anything, and I popped the second one. Then quite literally as I was standing talking to the tech, they kicked in and I started listing a few degrees off of vertical.
And, she put me in the machine, and stopped it after 10 minutes or so saying “there’s an artifact somewhere around your lower back, are you sure you’re not wearing metal?”. I was not, nor anything with metallic stitching. I said “Hmmm, maybe they left a piece of needle when they botched that epidural 21 years ago”. Anyway, she pulled me out, had me switch positions, and sent me back in the other direction. The artifact was still showing up, but not in the same spot (on me), so she wasn’t sure what it was - machine malfunction or something in the cushion, perhaps. Dunno what that was about. I’m sort of disappointed - I really wanna blame SOMETHING on that botched epidural I had :D.
