Good morning Steve,
I had been waking up with a fair degree of back discomfort. I exercise each morning including yoga and stretches and put this back ache down to ageing. I recently went on a search for stretches specifically for the back and found this.

My back immediately felt a little better and improved with each successive morning. Worth a try. Won't cost you and may be of benefit. Every back problem is different so.... I hope it works for you.
