There is a famous example of the fear, pain and joy concept told by Howard Schubiner, M.D., a leading pain researcher, of a construction worker who stepped on a nail that went through the sole of his boot and came out the top of the boot. Upon seeing the nail emerge through the top of his boot, the man began to scream in pain. He was taken to the emergency room, where he was given strong pain medication before they were able to get the boot off his foot. When they got the boot off his foot they discovered that the nail had gone between his toes and left no mark on his foot at all. So why did he experience pain? Because his brain was expecting it based on what he saw. That is the power of the brain – to create the sensation to protect the body from perceived danger.
This is an example of the power of the brain to create pain based on fear and expectation. It neuro-circuits in the brain causing the pain responding to danger signals. Because the sensation of pain is one of the brain’s responses to danger signals, any experience that increases the potential of danger signals can increase the possibility of pain signals.
Fear is one of those things that can increase the danger signal. For example, if a person has had an injury in their foot that resulted in pain while weight bearing, then they may, very understandably, fear bearing weight in the future. That fear will then turn on the danger signal in the brain and increase the likelihood of pain being experienced. It can become a vicious cycle.Continue reading.
