If the receptionist will not let you speak to the doctor right away, ask to speak to the nurse. Many times, the nurse will be able to give you the information that you need. When you speak to the nurse, ask for written information about your question. Sometimes they may even have videos or online resources for you to check out. Another good strategy is to call first thing in the morning when the office opens.
Most doctors have specific times set aside to return patients' phone calls.
If you are having trouble getting ahold of your doctor, try to find out from the receptionist what time your doctor usually returns calls. Make sure to be available at that time. You can also tell the receptionist when you will be available to speak to the doctor, and then make sure that you are by the phone at that time. Some doctors may even have an email address. If you are making an appointment and you know that you will have several things to discuss with your doctor, ask the receptionist for an extended, or double, appointment.
