Please look up deep myofascial tissue release, or MFR. There is a section here on it. It sounds like it’s your problem. The muscles in your back start working as groups instead of individually as they begin to glue together and then they put a strain on the connective tissue Which tugs on the bones. See if you can get it handled now as the issue, and you will age better. My long work hours as an artist at a drafting table (and the same with my father) created a problem, where the muscle fascia glued the muscles together, and they moved as a unit instead of sliding over each other individually. Start senior 30s if it’s work related and anatomical (our muscles began to weaken), also consider getting a Theracane (I use my grandmother’s old wooden walking cane) and I acupressure it into the offending pain in my back because no one is around to help me with massage. Become aware of your posture and take breaks during the day at work and do counter measure exercises. If it’s too deep internally, then you can try acupuncture and see if you get some relief.
