Calling all nurses or women who work at a Drs Office

I need to make a call to my OBGYN. I ended up contracting genital warts back in 2013 from an unfaithful ex (🙄)... I ended up getting them removed easily while in the doctors office and they said it was no biggy that they may never come back again.  
Well they did. How do I call to make an appointment for this? I am so utterly embarrassed. Does the receptionist at the doctors office seriously wanna know that I have warts? I just wanna make sure that when I go in it is something they can treat that day rather than having me come back. But I don't wanna look like an idiot and say too much over the phone 😩
