worrying is no good without the information. get all the information first. write down all questions and ask at doctor's appointment. ask them straight out - your concerns, etc. if you find you are not being heard, find another doctor if you can.
there are a million uncaring bad doctors out there. but there are good doctors, who care, who go out of their way to help you. these doctors are few and far between but they do exist and many have been mentioned on this forum.
