I'm a Paramedic, so I'd suggest that after a few weeks, Give NHS24/NHS Direct a call. After they've convinced you that you're having a heart attack, they'll send some of our boys round and they'll get you seen by the most appropriate person. Don't mention that you can't lift your pint as they'll mark you down as a boozer and you'll have to wait another week.

Seriously though, start with your own GP or NHS24/NHS Direct if during golfing hours. Worst case is a fracture and a sling or cast.
