Moderator's note -- the next 52 posts relate to an off-topic discussion on this thread. The thread was supposed to be about the BMJ and became about psychosomatic medicine. Therefore, the thread was split and any comments relating to psychosomatic medicine can be posted here. Is there any actual illness that has been proven to be psychosomatic; An illness where there are real symptoms and hundreds of thousands of sufferers? Can anyone name an illness that a substantial percentage of the population has which is thought to be psychosomatic?
