DR TCB, sorry to hear about your back. I too am having back problems and was off work Wed and Thursday because of it. It hurts mega!
I don't know what I have done to it, but at some point over the last year or so I messed something up and it comes back to haunt me now and then, but Wednesday was the worst and I had to have my supervisor drive me home
On the positive side, I am getting to know my hunky chiropractor intimately...um, so to speak.
I can move around much better today, thankfully.
