trichomoniasis
"Was diagnosed with Trich.  Dr. prescribed four 500 mgs of Flagyl to take at once.  Only complaint was metallic taste but it made me drink water more often and chew minty gum - I survived.  Unfortunately, it did not work.  6 weeks and 2 days later the discharge, itching, symptoms returned.  Note: I had not been with intimate with anyone, so it was not because of sexual contact, Flagyl just didn't work.  Returned to dr., was re-tested and it was positive for Trich.  Dr. prescribed Tinidazole the second time which I took yesterday; as soon as I reach or exceed 60-90 days with no symptoms, I will repost."
