Chronic pain sucks. One perspective to keep in mind is that just about everything in pain management varies drastically from person to person. Something that did nothing for the one person you talk to may work wonders for you, an vice versa. Frustrating as hell. It's a constant process of adjusting, adapting and recalibrating.
I started on this at 11, and I'm 48 now. So to me it is just life. Good days and bad days, and lots of "if I do that, I'll hurt for days" tossed into the decisions.
I wish you well in finding and keeping the comfort zone.
