Before many people buy a car, a television or a washing machine, they shop around for the best deal. Yet, when some of these people find themselves in a position in which a second medical opinion is a good idea – when facing a difficult operation, for example, – they are unwilling to go further. Sometimes it doesn't matter. But sometimes it can lead to the wrong treatment, even death. Health professionals say there are a variety of reasons why we fear that second opinion.A number of psychological roadblocks (障碍) get in the way of second medical opinions, but one of the most common ones is the fear of hurting the feelings of the doctor, and the possible result of that. People may think that in bringing up that they want to get a second opinion they are questioning the doctor's ability, so in the interest of not hurting the feeling of him they don't suggest it.Another reason people keep away from getting a second opinion is fear of the second doctor giving them worse news than the first. But the most important is that it's in your self-interest to get another opinion, and it may not be worse.Besides, most people respect their doctors, and regard them as with godlike qualities. So they trust their doctors are right, and don't ask for a second opinion. In fact, it doesn't even occur to them that they should. But you should remember that the doctor is a human being just like you.Finally, sickness may foster poor judgment. And sometimes, when people are sick, they become childlike. They put all types of good feelings onto the doctor and just let him take over. That might not be the best thing. Sometimes, obtaining that second opinion just seems like too much work or too much trouble.But remember, the purpose of a second opinion is to collect information so that you can make as informed a decision as possible on your medical care. Sometimes getting that second medical opinion can mean the difference between life and death.
