@coffeesackcat fellow suffers here!
is that what he said, or what you heard him say? There's an element of truth in it, I think, as my body over reacts to things. Maybe he misunderstood what someone explained to him.
There's a meme going around that pain is the body's way of expressing how much danger it thinks it's in.
Some of my pain went away after I did exercises to teach my body that certain movements were in fact 'safe'. I had chronic shoulder pain. I had to do this stupid little movement multiple times, always stopping before it hurt. Gradually the movement got a bit bigger. Now my shoulder functions normally.
So it's a very real illness, and it's compounded by the body over protecting itself. It shrieks 'pain, be careful!', at the smallest of triggers.
I feel a bit I've the princess and the pea. If I coddle myself and am really careful, I don't get much pain at all. If I live like I used to- pushing through, over doing it- then I'd be crippled on the sofa again, dreading standing up and wondering if I can manage the stairs to bed.
