Thank you all for the reply, I guess it was just unfortunate because the girl was only in her late 20's and wouldn't have much experience, I have been to a highly regarded orthopaedic consultant since and he advised to keep the sling on for 4 more weeks and to stay away from physios, he suggested that physiotherapy is no help to this injury andthat it need just the required rest and a few simple but consistent exercises to strenghten the muscles.

Don't worry physioONE, I have not lost faith in ye .
I'm going on holiday in 2 weeks time to thailand so I'm a bit worried about my arm. I was wondering about going swimming and the different strokes, are there some that would make me vulnerable and some that would help if performed gently.
Also I am wondering about the rowing machines you find in the gym if this would be a good exercise for my arm.
