I took metronidazole twice a day everyday for 7 days curing BV. I finished the pills on Monday. Wednesday I took two sips of my dad's long island ice tea & the next day my vagina started to hurt really bad when I took a shower. The next day when I looked at it, it was a lot of cottage cheese- like discharge with no smell but my vagina is swollen & hurts really bad.. please help I just want my vagina back to normal :(
