Please read my question about my broken collar bone situation and give advice?

I broke my collar bone just about a month ago. I went to my orthaepedic doctor last Tuesday and he did a follow up x ray and exam and said that it seemed like i was healing quite a bit slower than normal patients. He said that the bone is about 1.5 CM apart still but i shouldn't need surgery. Although most people at this time get to take off the figure eight brace that i am wearing, he said i should keep wearing it. He renewed my prescription for Vicodin and said i could call when i need a refill to get his authorization. I only have one left and had walgreens fax the authorization to the doctor last night and today the receptionist called. My doctor is on vacation and the other doctors will not authorize the refill. They think i have been on vicodin too long and should be taking just ibuprofen. I tried explaining to her that i am still in significant pain and that i do take ibuprofen but it doesn't really do anything. She was not helpful and didn't really seem to be very understanding whatsoever. I don't understand why these doctors who never examined me get to decide what's best when my real doctor said something completely different. What can i do to get rid of the pain once the vicodin wears off? I also heard that ibuprofen slows the healing process so i dont want to take any more than i am taking now. Anyone have any advice?
