Hello! I'm 25 And I Found A Mass Under The

Hello! I'm 25 and I found a mass under the skin of my vagina, located near the right side of the mons pubis region, below the hip. It's about the size of a grape and can be moved around. Its not visible above the skin and can only be identified by touch. I first noticed it about 3 months ago, and for the past month I have noticed a dull aching. Should I be concerned?
