There's plenty of tests that are less contrived. X-rays are done as a matter of course after treating a sprain. What would really be the costs of deferring them and only doing them when pain persists days later? Well, there's this (from http://www.foothealthfacts.org/Content.aspx?id=2827 http://www.foothealthfacts.org/Content.aspx?id=2827): "Patients with unrecognized ankle fractures have a high risk of developing infection, arthritis and foot deformities that may make it impossible to walk normally again." So what's your appetite for that risk?
