I have had my fair share of complications, aches and pains. With each injury I modify the workout and work my way back up - in this case down. :) Start with wall push-ups, then use your kitchen sink/counter, then bathroom sink, couch, step, and then floor. You can also do bench press. There are several rotator cuff exercises you can do to also help the recovery process.
I used to think - "Pain is temporary" but some pain you should not ignore. Especially when it comes to joints. Good luck!
