Writing thread titles is a sort of advertising. In the very brief space allowed one has to attract attention and give an idea of the subject matter. I felt very strongly that I wanted to warn fell runners, many of whom admit to and even recommend taking NSAIDs regularly, that they are dangerous.
Years ago, walking a GR in France, I took Diclofenac for about a fortnight so as to be able to continue despite two painful injuries. I knew I was taking a risk and decided it was worth it. Previously, I had taken all sorts of pain killers for migraines. Ever since I have had quite severe digestive problems and have completely given up taking pain killers including aspirin (paracetamol has never worked for me.) I found that my recovery rate from migraines was no worse without pain killers than with. I do attribute my digestive problems to NSAIDs; I am less sure whether they contributed to my A-Fib. I would not wish either condition on anyone. Given another chance I would NOT have taken Diclofenac in France, nor assorted strong pain killers for migraines. It makes my blood run cold to read about some runners' taking these drugs for quite trivial reasons.
I know that sometimes people have to make terrible choices, between agony and taking drugs they know are harming them. I just want people not in that dire position to realise that more and more serious side effects of NSAIDs are being discovered every day and that taking them eg to speed recovery after a race may cost more than most people would want to pay.
