I pinned 3cc in my delt once. It hurt, was warm, red and swollen bad for like 5 days. I was just about to go to docs and then it seemed to start reducing and then finnaly was gone. I think that 3cc in my delt just fucked me up. About being honest with doc it's not an easy decision. Obviously your health comes first, but i just went through a workers comp case where i just seen first hand that everything you ever (and i mean ever) said to your doc is documented and shared across the board. Careful what you say in your docs office. May come back to bite you in the aas.
