For many years, I was intimidated by doctors. I grew up thinking the doctor was always right. I have a crooked little finger that resulted from a doctor telling my mom it wasn't broken. It apparently was. It wasn't until I had children of my own that I learned the value of getting a second opinion when you have any question at all about your doctor's diagnosis or the treatment he or she may recommend.
Some days I think I am watching Spielberg's THX1138. Advertisements pelt us continually with news about one drug or another. Each new drug seems to be a miracle cure for whatever might ail us. Each ad suggests you "ask your doctor" about the drug. The inference is to ask your doctor to prescribe it.
