There is a hypnotic process where a suggestion is made that a simple act (eating a Tic-Tac or saying a phrase (or indeed a combination of simple acts) will make you believe that the pain has abated. As painkillers merely mask the pain, this is a psychological way of doing the same. It works by telling the body it feels the pain still, but not near as strongly.

This is not a cure for whatever is causing the pain, but may let you get a good night's sleep.

No, I don't know any practicioners personally who use this technique.
