Sir – May I thank publicly the expert-and sympathetic help I got from NHS staff on the night of Monday, May 11.

I thought I was having a heart attack, but it turned out to be no more than a muscle strain.

Nevertheless, the paramedics (Dawn, Simon, John, and Keith) and the hospital staff (nurses Laura and Neil, a doctor called Katy) took the case very seriously and treated me with all the technical expertise and kindness anyone could ever expect.

I am extremely grateful to all of them and very pleased that it ended in an anticlimax.
