help me find relief

so tuesday night i went to ER for a ruptured cyst on my ovary. well they did a wet pap and all of my STD tests came back negative. she then noticed i had a pelvic infection. right now i'm on clindamycin and now my vagina is inflamed, itchy, and tender. any tips on how to soothe that? i tried ice but there's gotta be something else. i eat a cup of yogurt every time i take a pill (twice a day). i read it's a side effect. so my dr can't do much.
