Agree that it's most likely your riding style. If you're bouncing up and thumping down at the trot, then it is jarring your back. Chances are you are tense, or out of balance to start with, and then curl your shoulders forward in self defense which starts a vicious cycle. Ask me how I know. Do a search for 'TxHorseman' and read a few of his posts regarding correct seat, which should help you get in your mind what a correct ,balanced seat should look like. It might/probably will take lessons to actually achieve it and learn what it feels like.
Also, the amount of bounce/jarring at the trot can vary greatly with each horse. Some horses offer a soft bounce that , if you have any where near a balanced seat, is a pleasure to ride. Others jar your teeth no matter how balanced you are.
It often is helpful if you can slow these horses down and get a better trot.
I wouldnt be cantering at all yet, if you're having back pain at the trot. I'd get that sorted out before advancing to canter. But, speaking of canter,,,your bottom should move in sync with the horse, and there shouldnt be any slapping of the saddle with your seat, ,,so it shouldnt cause back pain. (exception might be if you've had back surgery with a spinal fusion, but even that might not cause it)
I was an old/new rider at 57. You can do it !
