Before you leave the care of a physician, especially one you've been seeing for some time, you may want to have a discussion about why you're dissatisfied. Most doctors appreciate the courtesy and often find the feedback helpful. If you do decide that it's time to make a change, make sure you've found a new physician to assume your care before parting with your old one. You have the legal right to get a copy of your medical records, and they will help your new doctor in treating you. State laws vary, but you will probably need to make the request for a transfer of records in writing.
