The pain process is a complex and intelligent signalling system between the affected area of the body and the brain. This system is ultimately trying to protect us but it seems we can trick ourselves by making the pain sensation far worse relative to the injury.
In a recent article called "What happens when we feel pain?" I explored this pain process including questioning why pain can become persistent, how unhelpful thoughts play a role as well as best treatment and pain management techniques.
Here are two excellently presented, intriguing and entertaining videos by Professor Lorimer Moseley, a clinical scientist investigating pain in humans.
These are well worth a watch. Enjoy.
