You are solicited for an experimental study. Your primary care physician can help alleviate concerns about the protocol. Getting a second opinion is a common medical practice. In general, physicians appreciate people who are involved in their health care and encourage patients to seek second opinions for optimum care and peace of mind. By taking an active role in your medical situation, you give yourself a better chance of receiving top notch attention from the physicians most able to give it.
Doctors have specialties.
If you think another doctor may know more about your condition, or if you would simply like another opinion on a major procedure, don't be afraid to have your records forwarded. Although you may have a good relationship with your doctor, one that spans years, he or she simply can't predict everything that's on your mind. This is your health, so speak up. It's not a good time to be shy. Getting a second opinion is a good way to get additional expert advice from another doctor who knows a lot about treating your particular medical condition.
