In legal system when you are not satisfied with a judge, you re–appeal in the same court and if you are still not satisfied, you go to double bench before going to higher court.

Practice the same when you take a second opinion about your health.

Never go to a different doctor. First go to the same doctor and ask him to give his opinion again and, if you are not satisfied, then go to a team of two doctors and finally go to a doctor with qualification higher than the initial doctor. If your second opinion is from another doctor, it may be wrong or partial.
