How does the body map work?

The check-in includes a 3D body map: a figure you can spin freely to reach any area, with 76 named regions rather than a handful of rough zones. Tap a region (or find it in the search list) and set how bad it is; marks colour from mild to severe, and ongoing niggles show as recovering. It stays in step with the quick pain question in the check-in, so the two never disagree.
