Forearm and hand pain

Surgery was 2/4 rc repair. Aside from incredible sharp (same as pre surgery) pain in my shoulder when doing passive stretching I have this awful pain that goes down my forearm and into my wrist and hand/fingers. It’s not all the time but at this moment I cannot find a comfortable position and I don’t get what’s happening. I expected shoulder pain but this is just awful. Sometimes pins and needles in my fingers but the dull ache through my forearm is just wearing me down. I’m going in on Monday to have someone look at me. I was off the Percocet after about 2 weeks and didn’t want anymore but doc said yesterday that for this weekend to get the pain under control. I hate taking this shit. I’m a nurse and have seen so much addiction. I did not expect to be taking heavy drugs a month out. I went back to work pretty fast post op but it’s computer work and I have my keyboard in my lap. Maybe this is carpal tunnel IDK but I’m so over this. Rant over.
