Hey, I totally empathize with back injuries! Or at least lower back pain. In my case it's a semi-chronic lower back issue (not an injury), partly my fault for not keeping the core strengthened as I should at times, and it can just go out on me upon occasion. Really debilitating, to the point tying shoes is a chore! Like it gets charley-horsed or tied in a knot, then it takes a few days to "untie". Ugh! But hey, guess I'm just gettin' old, so get off my lawn!!
