as much as i would like to address your concerns i really have no way of doing this without an examination. there are so many things that could be called a "lump". i would suggest that you see your medical provider. this is really the only way that you can get a definitive patient-specific answer.
i have a lump right at the opening of my vagina. this is on the top of the vagina. is this normal? . i have never noticed this before.
