Fully agree. A physio once used an analogy which really resonated with me: think of your spine as the main pole in a tent. If the ropes are loose, it’ll be wobbly. When the ropes are tensioned properly the tent is solid.

If your problem is related to posture or being sedentary a lot (a common first-world problem) then gently rebuilding the strength in the muscles in your back will tension the guy ropes and make better posture happen naturally, often reducing pain at the same time.

Not medical advice - even gentle exercise could be exactly wrong for whatever ails you! But that analogy helped me understand that resting isn’t automatically good, even if it feels nice at the time.
