Hello Welcome to health care magic Thanks for your query. About 50 percent of the women are asymptomatic carriers of gardnerella infection. In your case secnidazode given for gardnerella infection is relevant, further clindamycin 2 percent cream applied locally is also effective added with Lactel (Protein - free acidifying lactate gel which neutralizes the vaginal pH) - 5 ml can be applied daily for 7 days. Gardnerella infection recurs in 30 percent of the cases. But in some cases the infection can cause pelvic inflammatory disease. If the problem persists investigations can be done to rule out pelvic inflammatory disease such as cervical and high vaginal swab culture for both aerobic and anaerobic organisms. Imaging studies can be done after consulting a gynecologist. Consult gynecologist and take further suggestions. Wish you a good health. Dr.Kidev.S
