Some personal evidence: I obtained relief by installing a traction bar high enough my feet don't touch the ground, and remaining suspended for some time, a few times a day every day. It took me a couple of years to develop forearm muscles strong enough to withstand more than 30 sec, and to learn to fully relax the back so it stretches freely. Particularly effective when coupled with a warming up (at the beginning, from simply walking a few miles, couldn't do much else). Can now even do that when crises arise (even when cannot easily walk). Works also in the morning on cold muscles, but some small tendinitis In elbows can follow. In this part of the world, insurance-covered doctors are very sceptical when you turn in with the back pain, and physio offer very basic things, no real relief. I did take a scanner and other tests, to evaluate the situation. Disclaimer: this is not a medical advice, I am not a doctor, "back pain" is a very broad definition.
