Physicians are trained to diagnose and treat disease. When the answer isn't apparent, or if the complaint is particularly vague ("I feel dizzy"), it can be difficult to make a firm diagnosis.

Some doctors may be inclined to say that your complaints are nothing to worry about or are psychosomatic — i.e., "they're all in your head."

While anxiety and stress can play a role in how healthy you feel, you should always remember that you know your body better than anyone else. Be your own advocate and ask questions like: "How do you know it is in my head? How do you know it is nothing? How do you know it is not a heart attack?"

Insist that your doctor take the time to explain the tests and reasoning behind the diagnosis. If he or she is unwilling to do so, or doesn't explain the diagnosis clearly/or is unclear in his or her explanation, find another doctor.
