Hi there I had all three procedures as you and yes, it is difficult to raise your arm for a while. I am 4 weeks post-op and couldn't raise my arm very much at all at first. I find if you keep your elbow in and raise a little more each day, the ROM will start to come back. At the first sign of pain, you must stop. Do not push it, and listen to your body. I would usually start light stretches to raise as comfortably as I could after a nice hot shower to loosen up some of the tension. To give you can idea - after 2wks post-op I went to PT and was measured. I could raise my arm about 80 degrees, now I am 4wks post-op and I can raise it about 120 degrees. I hope this helps you Best of luck to you in your recovery.
