Shoulder Specialist. We need more information about the full extent of your diagnosis...I recommend you get a second opinion with a shoulder specialist. http://www.theshouldercenter.com/shoulderpain/2012/shoulder-specialist/surgeryspecialist/http://www.theshouldercenter.com/video-how-to-choose-a-surgeon-for-your-rotator-cuff-repair.htm these links may help you make a more informed decision.
Rotator cuff. Would get a second opinion. Sounds like you are still having shoulder problems. Would recommend another ortho surgeon or physical medicine or sports medicine physician.
Probably didn't heal. I suspect your repair didn't take which unfortunately a known risk of surgery. If you still have pain and crepitance you probably need to be further evaluated. I would recommend a shoulder specialist as based on your age there still are options such as reverse arthroplasty. Really hard to give specifics without formal evaluation.
