Something like this happened to a friend, she was in deep pain but they said her treatment would be on hold just to wait for a test results. A day went by and they haven't informed her yet, so he went to a walk-in clinic for a second opinion, the Dr. gave her something to ease her pain immediately and pushed for a minor surgery.

Who knows what might have happened if she waited for her GP's call. Lesson is if you are not satisfied with the treatment they give you go to another doc for confirmation.
