Funnily enough, I have just had a long chat about drugs. He knows I can't tolerate strong pain killers and is so kind. Over the years, I have built up a very high pain threshold, because of my reactions to so many painkillers (and other drugs) and also because of being taught coping strategies and attending courses. There are many of us and my doc says it's because of my metabolism. I would rather suffer pain than being out of my head hallucinating and being zombie like. I recently had a hernia op with no pain killers after the op except paracetamol. My shoulder replacement pain after the op was managed with nerve blockers, and nothing extra after they wore off.
