I felt pain around the skin on my vagina. Well, today I have a lump quarter sized or larger?

I’m a 24 year old female with no past medical history. I’m only on the Nexplanon birth control rod implant in my arm.

A few days ago, I felt pain around the skin on my vagina. I felt and there was a penny sized lump that was hard as a rock. I figured it might just be a bad zit and I would give it a chance to come to a head. Well, today the lump is quarter sized or larger and it still hasn’t come to a head. The lump is very hard and very very painful. It feels like I can almost “roll” the lump under my skin. I can barley walk, sit or stand because of the pain. Should I go to the ER? Urgent Care is closed and I don’t have a family doctor right now. The pain is becoming unbearable.
