I just had to change up my routine because I irritated my shoulder joints. The way to work with that type of injury is to find exercises that don't cause immediate discomfort/pain while doing them, and don't make it feel worse afterward. Take a very basic 3 or 4 day work out split and customize it using this approach. It will be a learning experience that you will benefit from in many ways. Keep your reps in the 10-12 range with strict form and a good squeeze at the full contraction point.
Don't worry about what the doctor says, just keep a work out journal and get your diet together.
