Going by your symptoms, it looks like bacterial vagino
sis to me. It is the most common cause of abno
rmal vaginal odor
. In addition to unpleasant "fishy" vaginal odor
, thin white or yellowish discharge
from vagina may also be present. Diagno
sis can be confirmed after pelvic examination and microscopic examination of the vaginal discharge
. Treatment is by metronidazole and clindamycin.
The other possibility which should be ruled out is of a rectovaginal fistula.
