I get lots of back pains, it's always clicking I just live with it. I even compressed my lover 5 vertebra one time couldn’t ride for about 3 4 weeks I think and even after that time it heart like hell and I was at risk of compressing it again.
I always do that thing where you lie on your back and bend you knees up and then put you legs over to one side twisting your hips. Then it clicks and feels good again.
When I put my shoulders forwards all down the top of my spine clicks.
Well to think of it almost all my joints click all the time.
