The body has no memory for pain. We are incapable of vividly retrieving the sensation of pain once its occurance is over. That said, I am very well able to recall the disturbing, reality narrowing tunnel of agony you endure when pain is inflicted upon you (physical pain that is, not its mental equivalent). So far, I have been lucky where physical pain is concerned. Only three times in my life thus far, I experienced physical pain beyond what I thought was possible, or endurable for that matter. Bear in mind, I am of the weaker kind.
