Does any of this apply?
Book an appointment
Arrange a routine appointment if you notice a new vaginal or vulvar lump, even if it is painless.
Assessment is also appropriate if a known cyst grows, keeps returning, or begins to interfere with sex, tampon use, exercise, or urination.
Every sign above is quoted from the sofidex article on Vaginal cysts. If you are not sure, err upward — it is always reasonable to be checked.
