Welcome to the forum! Sorry to hear about your back troubles. Absolutely not fun. One of those things that you never fully realize how much you use until it hurts.
As far as after, therefore because. Hard to say. I know I had upper back / shoulder pain from the rib spreaders. Beyond that, it’s been 13 years since my last. Things get a bit fuzzy over time. Is it because of time in the table, or just getting older? Mostly lower back these days so I assume it’s age.
