In reply to sarah79:
I had a hip Arthroscope just over 5 weeks ago to repair torn cartilage and a bit of reshaping of my bones! Apparantly its a bit more serious than a shoulder or knee one and I'm almost back to normal already. For about 2 days after it was painful but I didn't need any painkillers, just rest.
You don't need to worry about it, it'll be fine. Just be prepared to take it easy for a while afterwards.
Goodluck
