I have a problem with the muscles in my lower back tearing alot. Most of the time it is on the right side.
I had a bad fall from a tree when I was around 11. I fell from about 12 -14 foot and landed flat on my back.
I was a concreter in my late teens up into my mid 20's and for the last 10 years or so throw around cartons of beer and wine all day.
The little side bits of bone in the disc above my pelvis have grown at a odd angle and every now and then I will move in a weird way causing it to press on the nerves then it flairs up for a week or so.
I have had lower back pain for as long as I can remember. I always find it plays up more in winter.
Found some of the stretches described by Bazz61 helps. I try to do these for around 15 mins each night while the missus is watching neighbours or what ever

I have surfed my whole life from around 12 years old.
Also I know I am gonna cop it for this but, About 3 years ago I donned the Lycra ( Yes I Know


) But honestly It has made a big improvement and my back doesn't hurt no where near as much as it did before this.
