Hi there Dace

the pain seems to come on just when i hit around 90 with external rotation, carrying heavy things brings on a very slight ache but not the sharp pain it presents normally with.

It is painful to sleep on that shoulder but bearable, press ups feel fine, on palpation theres no noticeable areas of tenderness, hand behind back and lift off fine, hawkins kennedy -ve.

Not too sure what you meant bu this bit "And by flexing the arm to 90deg is that to the front to side"

Thanks for the help
