lump inside vagina

[teppikath]

one day i feel all little pain in my inner labia inside my vagina when i check it, its a pea size bump that very uncomfortable. i did sitz baths and warm compress and it feels normal again.. and in several days inl feel the pain again and the lymp inside feels back and grows bigger.. i didnt have experience pain when pee (urination) or white discharge like the internet was saying, no bleeding, I dont have fever too; but this condition really stressing me out.. and lately i feel luke im bloated or full and anytime i could have my period (menstruation) but not any sign.. im really worried i was imagining that this lunp goes bigger and bigger.. what should i do.. should i do sitz bath again
