Re: Ice off, made it out.
And best of luck with the surgery! I had L5/S1 disk removed in late '84 and wast trouble free until 2010. Twisted it bad in 2010 doing some ladder work (it's no wonder I was an rescue & engine guy all these years - can't stand ladder work!). Anyway, a couple of weeks of rest and a cortisone shot, and the back's been trouble free since....
