I guess in that case there isn't much you can do apart from educating the new doctor. Annoying, but it will happen to all of us one time or another as doctors retire or move etc.
Just makes you wonder how you would actually go about explaining your medical history to a new doctor.
The records are probably brief, and would be notes for the doctor's benefit or understanding, and may not mean the same to others.
I suggest that you write up your medical history as best you can, inclusive but brief, as they don't like to spend more than a few minutes on patient notes.
This is actually a good chance to put your perspective across and to ensure that your history is properly recorded.
May be a blessing in disguise.
Treat it as a positive, I say.
