I dislocated mine 2 years ago with a similar result. Didn't go back in without the aid of three people and lots of morphine. I got full range after 6 weeks without physio. I went back to work in the forest a week after the dislocation. If you can, take it easy cause shoulders are prone to reoccur after the fact. Be adamant with the physio and keep strengthening and stretching. In other words don't be a slacker, then once you feel you're ready; go riding!
