Hi all, apologies if this has already been asked but one of the late Dr Sarno's theories about pain was that it could be explained by mild deprivation of oxygen to the part of the body afflicted by pain. I have no trouble accepting this but how would you explain the pain experienced by amputees in their phantom limbs? Clearly this can't result from reduced blood flow and oxygen deprivation. So either the good Doctor either didn't have it quite right or pain can also solely be caused by some sort of neurological process in the brain, one that involves an illusion (some might argue that the way the brain constructs our total reality is illusory, but that's possibly a whole PhD's worth of reply). Can someone please clarify or point me towards the info that might explain this. Many thanks.
