Hi, sorry to hear about your RC problem. I haven't been around these forums a lot, so please excuse me if you have talked about these and I am not familiar with the story.
Q1: Did you do a rehab program after the sprain?
Q2: Wave you been evaluated recently to know how you are doing?
Q3: What exercises produce pain?
Q4: Can you post/pm a side shot of yourself, hands down?
Oh, and I am sorry I don't own OPT so I don't know what DB get ups are.
After seeing what you say I might be able to suggest some modifications
