HELP!!! PLEASE READ

KS❤️ • Dealing with PCOS
I used to get bartholin cysts before but didn't get them this year until now that i started feeling sore and i looked at my vagina in the mirror, didn't see anything but when i touch it i feel it! Honestly this one is SO close the opening that I hesistated but still used my remedy of putting tea tree oil with witch hazel but I'm afraid i might cause more harm if that mixture goes into my vagina! Anyone think i could get an infection if it the tea tree oil and witch hazel goes inside? Ughhh I really don't want it grow!! Please help. ANY EFFECTIVE REMEDY?! Except for sitz bath. Thank you very much!
