Thanks UL730, the sports physician has referred me for MRI and arthrogram which I'm doing next week.
Gingernut, I'm 46, been doing karate for 30 years and don't intend to put the Gi on Ebay just yet! Never liked sparring so avoid that, at my age it's about focus and technique rather than speed and power, no contact stuff. The best thing I know for for anger management, stretching and flexibility and forces me to use both legs equally which I don't otherwise.
Walking (and stairs) is pretty painful so don't think I'd get very far on a golf course! I'd need one of those little car things, which seems like cheating to me
