Thank you for your reply,

With regards to the estimated cause of the pain, how long do you feel the injury will require to heal sufficiently for me to partake in weight lifting again. As i mentioned the only lifts i have problems with are dips and bench press, also anything which places the arm in outstreched perpendicular position to the body, ie lateral raises.

I have started to attempt to do some Wikipedia reference-linkrotator cuff exercises but the affected arm is still to sharp to do them properly.
