I've had a vaginal odor since my partial hysterectomy with no std diagnosis or exposure. is there something i can take to re-balance my environment?

Bacterial vaginosis?: The main cause of strong vaginal odor, sometimes with discharge, is bacterial vaginosis, an overgrowth of mostly normal vaginal bacteria. Hysterectomy might trigger it. The doctor who did your hysterectomy undoubtedly has a lot of experiecne with BV. Contact her for advice on diagnosis and treatment. It is unlikely you can accurately sort this out without professional evaluation. Good luck!
