Just back to work fell tore rotator cuff, minium 3 months off work if you do manual work after surgery which in my case took 5 month wait after accident . 6 weeks in sling and then physio to get your arm working again which it will not do without a lot of excercises. 5 months know since surgery and can do most things I did think will I bother getting surgery but glad I did now.If you can not lift your hand above your head it will probable be a rotator cuff tear.
