From Rosemary Sharples, Sydney, Australia
I'm glad to see that someone else has noticed that there is a difference between pain and suffering. You report that silencing brain cells in mice can make them no longer care about pain (26 January, p 19).
The first time I was given opioids, I waited for the pain to go away, but the “painkiller” didn't seem to have any effect. The second time, I realised that it wasn't making the pain go away, but did make it easier to tolerate.
