The short explanation
A small painless lump near the vaginal opening is usually caused by something harmless. Common causes include a Bartholin's cyst, which forms when a small gland near the opening gets blocked and fills with fluid; a blocked sweat or oil gland; an ingrown hair; or a small skin cyst. Many of these stay small and painless and some settle by themselves. It is still worth having it looked at, because a clinician can tell what it is by examining it. Less commonly, lumps can be caused by genital warts or, rarely, by something that needs further tests, and a quick examination sorts out which is which.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- A lump that grows, becomes painful, red or hot, bleeds, or develops an open sore is more urgent than one that stays the same.
- Shaving and waxing often cause small bumps and ingrown hairs in this area.
- Bartholin's cysts can appear at any age but are most common in women of reproductive age. A new lump after menopause is more likely to need checking.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot tell you what your lump is. Only an examination, and occasionally a small test, can.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- What do you think the lump is?
- Does it need any treatment, or can it be watched?
- What changes should make me come back?
- Is any test needed to be sure?
When to seek help
Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.
Get help the same day
- Get care the same day if the lump becomes very painful, swollen, red or hot, or you develop a fever.
Book an appointment soon
- See a clinician within a few days if the lump is getting bigger, bleeding, or you notice a sore.
Raise it at a routine appointment
- Book a routine appointment for a small painless lump that has stayed the same. You can ask for a woman doctor, and you can bring a friend or relative into the room with you if that helps.
