I agree fully. And even just little changes can make a big difference with Back Pain. Just do some simple experiments. Raise your bars 2cm, Lower your seat 2cm, move your seat forward 1cm, then give it a try. You can mark your current settings to get back to them if needed. Even if your bike has been professionally fitted give these things a try. Back Pain is a BUGGER!!!
