Suggest Treatment For Shoulder Injury

I hurt my shoulder in rugby, I saw a doctor and he took an xray but couldnt confirm what was wrong due to financial difficultys I couldnt see him agaiin. I started wearing a shoulderbrace and thought it would heal with time , its been about four months now and my shoulder still hurts when I throw a ball or lift myself up with my arms...Is this the result of a torn rotator cuff ? and what can I do to heal my shoulder?
