Hi and welcome.
No, I wouldn't think that you need to make an appointment. Talk to the receptionist and tell him/her what you've already had done. If she says that you need to come in to be assessed, move on to the next office.
The receptionist in an office is supposed to be your ally, not a wall between you and the doctor. Honest, if they can't help you, then you ought to move onto the next office.
