Routine appointments with the doctor are for ten minutes and for one ailment. This means that they has time to listen to what you have to say, take details of how long it's been going on and what else is happening that might be causing the problem. Then, you may need to be examined, a test may be needed and you may need a prescription. All of this needs the ten minutes allocated to you.
For more than one problem, ask the receptionist to book a double appointment.
Please don't bring along the rest of your family for the same appointment time with the doctor. Patients who come in and stay longer than their allotted time keep others waiting past their appointment time.
