Dr. Hanif warmly welcomes you! Thanks for consulting at my virtual clinic. I have carefully worked through your case, and can well realize your health worries. Being your physician, I want to assure, I will take care all of your medical concerns. It seems to be due to vaginal infection, and it has no link with tanning episode. If I was your treating physician, and I confirmed the bacterial vaginosis as the treatment, I would have prescribed you clindamycin antibiotic to be taken orally if not allergic to. There is another differential diagnosis and that is yeast infection of vagina and needs antifungals like Clotrimazole vaginal creams to be applied in vagina. You need a visit to gynecologist for proper treatment and prescription of the drugs mentioned above. She will have the benefit of physical examination and diagnostic procedures to reach to a diagnosis. Avoid sex and alcohol during the treatment period. Hope I answered all of your questions. In future, if you need further, detailed and quick assistance on any health issue, feel free to click on Ask me a question directly from my profile. Have a wonderful time ahead. Regards! DR.
