yep, did my back 20 years ago. Lower down and now I have a disc sitting slightly out, which I can feel.
I am just very careful these days. I dont leap about like I used to (think Sting, jumnping out and down) and I sure don't carry heavy stuff these days
All bass gear is class D, I don't use any backline on duo gigs and no monitors now as I have gone IEM
I do still lug the PA about but thats as light as it can be, QSC K12s and Ksubs
