I've found the same to be true for running: if I continue running (or more accurately, limping) on a sprain, and massage the area when I get back home, the sprain usually heals within a few hours and I can run again the next day as if nothing happened. OTOH, if I stop running, and either ice the injury or take painkillers, it takes almost a week for the sprain to heal.
