How to disagree with your doctor
Bring an advocate with you to appointments.
If you're in doubt that you and your doctor are agreeing on treatments or communicating well in general, try bringing a support person with you. This can be a relative or trusted friend.
Talk to this person about your condition ahead of time, and tell them why you're having doubts about the treatments or suggestions your doctor is making. Let your support person know that you'd like them to ask the doctor questions too, if they have any during the appointment.
