I would like to know if there are any alternatives to metronidazole? thank you so much for your help.

Yeast?: The main vaginal infections treated with metronidazole are trichomonas and bacterial vaginosis. Your symptoms don't suggest either one. They are typical of a yeast infection. You could try an over-the-counter yeast cream or suppository (look for active ingredient ending in "azole" (clotrimazole, miconazole, etc). If that doesn't work, see a doctor or clinic for diagnsis and treatment. Good luck!
