As mentioned by previous posters, pain is a defence mechanism and ultimately a survival mechanism; the body's way of alerting the brain to harm so
that we will take action to avoid further/repeated harm, or to actively treat illness or injury. Without pain, we would have little immediate
motivation to avoid danger, we would take much longer to learn from injury, and our survival instincts would be severely reduced. Hence the phrase:
"Pain is the greatest teacher of all."
Pain works very well in alerting the brain to harm, however it is an incomplete and ultimately flawed system since there is no way for the brain to
switch off the pain message. Hence there are millions of people living with severe and constant pain for conditions that are untreatable yet
not life-threatening. This is the horrible, human condition of pain. And if chronic pain leads one to commit suicide or seek euthanasia, has pain not
then failed in its purpose to protect us from harm...?
