I've been dealing with lower back and leg issues for several years and find that heavy instruments exacerbates the problem.
I've developed several strategies to cope:
I modified some heavier instruments to be played on a Steinberber EUB stand so I can stand or sit and play without holding anything. It's my "Bass-on-a-Stick" solution. I've received more questions and comments on that setup than any instrument I ever had.
My fretless "Bass-on-a-Stick": The actual bass weighs over 10 lbs but I don't feel an ounce of it while playing.

I've assembled light 34 inch scale solid body basses from parts. One weighs in at just under 6 lbs. and another is 6.75 lb that balances a bit better. Either on a neoprene strap almost feels like I'm not wearing a bass at all.
The 6 pounder:

I also pack a light stool or folding chair so I can sit while playing when necessary.
Good luck with your quest and your back.
