Hi and thanks for posting

Cysts or lumps like these can be common and if they don't become infected, don't necessarily cause problems. They may be due to a Bartholins cyst or a blocked sebaceous gland.

We would always though, encourage people to get them checked out by the GP or family doctor though just to make sure. Sometimes, antibiotics may be needed if it starts getting painful or inflamed ,so you would need to get these prescribed by the doctor. They rarely need to be removed.

In the UK if you are over 16 you can make your own appointment at the GP(family doctor) without needing a parent or adult to go with you, though it's usually best if you can talk it through with a parent or trusted adult. Try and talk to your mum about it imagining the lump was on your arm or leg, or you could write it down if you feel you can't talk about it.

I hope you manage to get it checked out

All the best

Wanda
