Healing your Back
glenn.substack.com
A while ago I wrote an article of all the things I've tried to get rid of my back pain, and it's a pretty comprehensive list. Unfortunately, because of a motorcycle accident many years ago, I have a lot of experience with back pain.
I found another article that handles this issue in depth, and I think it's pretty darn good (the main thing they miss is Active Release Technique - learn more in my previous article). I hope this helps you!
