Weird but painful lump in my vagina

Hi, I have some issues on my vagina there’s a lump inside and I can’t see it but when i touched it it’s painful everytime i sit . I don’t know what is this. Please give me some advice and I can’t tell this to my mom.

You need to describe it much better if you expect someone to be able to help. Even better, if you have issues - visit a doctor and get it professionally examined.
