I think this can be broken down into two problems. 1. Preventing / curing all causes of pain. 2. Changing how the body responds to pain. I think problem number 2 is easier to solve. The human body is a biological machine and I hink we will find better ways of handling pain than today. An example could be an implant in the brain that simply blocks the impulses.
