I have chronic bv. Maybe an infection every other month. Medications are different. There could be some burning,itching, lumpy discharge,or a yeast infection could develope.No one knows why bv starts.I sweat so bad in my vaginal area that I have to change my panties durung the day.It is best to sleep w/o panties so that u can smell ordor from the vagina.Go online and out in bacteria vaginsis.The smells are different.If you smell musty,sweaty,fishy,or just stank, you have an infection.When in doubt sniff your panties. Plus cut out sugar and carbs.Try the herb black walnut
