"From what I’ve heard about pain killing placebos is that they don’t actually work when measuring pain objectively - which is usually done with a range of motion test. A person on a placebo will say they feel better and the pain is less bothersome, but when they are asked to lift their arm up, as in the case of shoulder pain, they can’t actually lift it any higher. With a real pain killer they can - although maybe they shouldn’t!"
