Michael Sullivan discusses the relationship of neurons and the experience of pain as well as one possible protocol for re-training neurons to experience pain differently via visualization and suggestion at http://mg.co.za/article/2011-03-11-train-your-neurons-to-ease-the-pain/. I use a different protocol but regardless of the approach, suggestion has been shown to be very effective in alleviating the experience of pain or discomfort. This is important as many folks experience some degree of chronic pain, one South African study put it at over 48% of the population suffering from some sort of chronic pain experience.

All the best,
