Granta has published a short piece by me on running and not running as part of its 'exit strategies' series. Since I wrote it I have heard from my GP that the X-ray shows no indication of osteoarthritis, and I am in the clear. (The pain and swelling in my knee may be the result of running in shoes that were worn out and other factors. After more than a month's rest I'm feeling fine, and am starting - cautiously - to run again.)
Anyway, I can say 'got better', at least for now. Any resemblance I may bear to a newt is down to something else.
