there is no reason you should leave a doctors office and not have your questions answered, i had a doctor like this before and thought well he must be a busy person and doesnt have time to answer and explain, well that didnt meet my standards of a doctor, so i switched and the doctor i have now will answer all my questions till i understand the reason behind the answer, now when i go into see him he says did you bring your list of questions!! i feel better knowing this doctor takes time to make sure i know what is going on
