I find that well-executed strength training (i.e. with proper form) eliminates all kinds of back-related issues for me. This talk has been really eye opening for me:
+1 on this, for me deadlifting has single-handedly fixed my back. I tried PT for it, with mixed results, but once I started lifting it completely went away. YMMV, but it's worth considering for sure.
I'm clearly doing something wrong, but lifting has driven every time I've injured my back in the past 5 years. I've had trainers coach me on form, and _most_ of the time I'm fine. But if I have bad form p% of the time (e.g. 0.5-3%), and working out becomes a ~daily thing, then I have a handful of opportunities per year to injure myself.
You kind of provide recipe how to avoid it yourself. One suggestion that might or might not be relevant - don't do weightlifting at your proper max, and don't push your limits that way. Its a way to grow fast but also sure way to injury. There is no way to be at your limit and keep the proper perfect form, every time. You can always add more repetitions to workout.
For me weightlifting is about staying in shape for things like mountain adventures, feeling great, looking good. But Arnold-look is a silly goal for long term wellness, and so are the methods to get there. Once I stopped pushing the numbers and focused on more repetitions, I never had any injury. That's worth much more than some momentary number of kilos/pounds you did today - nobody will care about that tomorrow, but injuries remain, sometimes forever.
YMMV, but I found the following articles quite useful to 1) help self-manage symptoms brought on during strength training, and 2) to stop obsessing about my using "bad" form during training:
