Keep pushing the doctor. If the current doctor does not respond find another doctor in the same area to talk to about the concerns. Don't be afraid to step on a doctor's toes. It is humanly impossible for one human being (including doctors) to know everything about everything. Every doctor has a different box of experience with patients and different interests in his or her field to draw on to help patients. I have never been afraid to step on toes or go find somebody else to talk to about my health concerns when necessary.
