Red bump on outer vaginal lip? ?

I have one red, hard lump on my outer vaginal lip/labia majora. I am not sexually active and never have been (I'm a virgin). It's a bit itchy but other than that it only hurts when it's touched. It looks like maybe it could've been dried out and then scar tissue built up maybe. I can't tell because it's at an awkward angle. Could anyone tell me what it could possibly be? Maybe a swollen bartholin gland? I'm not sure and I'm a bit (majorly) worried.
