Pain management guilt...

So in 2010 I was hit by a car whole crossing the street. I fractured numerous bones in my left shoulder and arm so I have a metal plate and 10 screws. Last week at work I went to reach for something and I heard my arm pop. It's been in extreme pain ever since. For three nights I didn't sleep well so Sunday night I went to the ER. The xrays came back fine but they did give me a prescription for percocet. I feel so guilty taking them. So far I only take one before bed so I can sleep. I have an appointment with my orthopedic surgeon tomorrow to figure this out. I'm currently using my sling I purchased a couple years ago when something similar happened. Pain management is near impossible when pregnant. I really hope I can get some solutions tomorrow.
