Since you are the subject of the file, you have immediate access to it and are entitled to do with it as you please. Especially so as you paid for every single IRM, X-ray, amnioscopy - whatever it is.
The doctor might not like it that you go see someone else but there is no rule forbidding you to move over your file.
You might want to see Mrs.
Panarello , I am told good things about her.
