Some more anecdotal evidence I was hospitalized with a huge abscess that was damaging my leg and hitting my sciatic nerve. The pain was as acute as I would imagine is possible. The morphine drip that I had did nothing. It was very frustrating. Sometimes the pain would re-occur before I was allowed to get more morphine, and the duration/severity of the pain was comparable. At the time, I thought that the morphine only managed to make me tired after the pain had subsided, but maybe taking a nap after that kind of pain was normal anyways?
