Ive had this issue myself for many years, started very easy for me in my 20's.
Here is what I do that give some some relief.
Buy each of these, they are worth their weight in gold. I own over 30 different traction devises, and I buy everything new I can find when I come across it, and these are any far the best.
this is great to lay on to get the spinal erectors to release.

this thing is awesome, I use it every evening and it will do wonders for you back. it allows you to relax more when you lay over it, allowing the muscles ton relate and the spine to pull and give you great traction for the lower back.

I have a routine of laying on these every evening to help me get some traction tony spine. The trick I have food is laying on this right before bed, as in do everything before you get on this, once your done crawl to your bed and lay in it. You will see that the lower back is nice and stretched out and you will sleep so much better and wake up in far less pain. This has made the difference in my life big time, it allows me to function with some normalcy in my life. Hope this helps!
