Hello Please Am Worried For The Past Days Not Up

hello please am worried for the past days not up to a week now i have been having serious vagina itches it doesn't hurt it's like having filaria once you start scratching you can't let go easily but because of the constant scratches my vagina is paining. I don't know if it's an infection I contracted from a toilet or something because I have not had sex for more than a month and even so it was safe. I pray I find answers here with you. thanks
