Bump on Vagina PLEASE HELP

hey everyone! so i have this “bump” ( i would describe it more as a mound lol because it’s more wide than tall) on the skin above my vagina (right where i shave) it’s pretty painful to touch and looks a little red and irritated. i’m wondering if it could be an ingrown hair, or possibly something else? i’m not sexually active, and never have been so i’m positive it cannot be an STD. how can i get rid of this?
