Doctors?? What's procedure

I went to the ER today because I had a boil on my labia the size of a golf ball. The doctor comes in an asks to see it. It was right at the top of the labia no where near the opening of the vagina yet the doctor decides to check down there and inserts a little bit of his finger in me. Not until I tell him no it's not right there does he stop and say yes I see it. (It was impossible to miss you could see it even if my legs were closed) Is this procedure or am I overreacting?? I mean you could clearly see that it was no where near there because it was seriously the size of a golf ball
