Got one of these to hang upside down for a bit and stretch it out a few times ?? Temporary relief from the squished out vertebra pushing on the nerves.

My experience with back issues is that the back and leg muscles tighten up so much that they pull down hard on your spine, pinching the nerves in the spine at the points where they are close enough to start squeezing on the nerves.
Found this out from sitting in a chair for 10 hours a day doing computer service work, dang muscles shorten up (causing back troubles) when they are not getting stretched out, like they do when you are out walking around all day.
Got out of that career and sitting in that chair, out and about doing stand up things in the shop now. Back has been back to good again now for many years.
Good luck
Hate to say it but, 1 shot of whiskey for a muscle relaxer might help the tight muscles let go to at least let you get to sleep.
