i have this same problem. now that i'm sure (or nearly sure, i guess most people can never be 100%, and that's normal) that it's not structural, my fear is of the pain itself and i struggle with the constant battle of should i baby myself, or should i live my life? if i do the things I love, like certain exercises, i for sure exascerbate my pain. However, is the pain getting worse because of the exercise, or is it getting worse because I FEAR it will get worse from the movement, so it does? I think regardless of what is happening, we are so conditioned to fear the pain itself that it almost doesnt matter why we are fearing the pain, it matters that we DO fear the pain. we are conditioned to fear the pain. And why wouldnt we? It sucks!
