I feel your pain!
Or at least I feel some pain, and thus can relate (my current burden is spondylolisthesis (T12 done went and slud back on L1 and is pressing against the spinal cord) and an utter and complete lack of disc material betwixt L5 & S1 - which the evil AI says is "a rare and significant condition, often a result of advanced degenerative disc disease or injury. This can lead to instability in the lumbar spine, potentially causing pain, nerve compression, and other complications."
May 28 they're going to put spacer cages in those 2 places & fuse L2-S1 and then (the hardware for that fusion being a long-ass lever & S1 being a tiny bone) out onto the pelvis.
Recovery from which will be complicated by the fact that Senior Management went in April 3 & had Her C2-C5 fusion extended to C2-T3; brought Her home Monday.
Remember that lever thing I mentioned? Saturday it fractured T3 where the screws went in, & pressed a piece into the spinal cord hard enough that She couldn't stand; Monday they went back in, relieved the pressure, and fused C2-T6. Don't know when She'll get out of the hospital - but when She does, it will be to move to a residential acute rehab facility (those of you have been around 5 years or more may recall my own adventures in such as establishment.....) for an undetermined length of time.
All of which is a long, round-about way of saying "Damn! That sucks, and I have an idea just how badly!"
Take care, Been; follow the medicos' instructions closely, go slow, and take Bill's advise to heart. Remember, sitting worked just fine for Skunk Baxter, Tal Farlow, plenty of other jazz pickers, most keyboardists & drummers, etc., the overwhelming bulk of classical and Dixieland cats, and so on. No shame to it.
Hope you heal soon & well.
Peter (who, no, will not be playing fusion music after......)
