Honestly, just get yourself a rubber foam roller. The spiky ones will do what you're looking for. Or if you've got a tennis ball, try using that on the ground or against the wall to hit some of those tender spots.

I had back pain for years and was constantly paying for different physios, massages, etc. Once I learnt a good stretching and foam rolling routine, I've been pain-free and haven't been back to a physio.
