The burning discomfort in the vagina is not necessarily bacterial vaginosis, it is mostly caused by vaginal inflammation leading to increased secretions and irritation to the vagina. In addition to bacterial vaginosis, there may be trichomoniasis, mycosis vaginitis, etc. Oral metronidazole, fluconazole, etc. can be taken under the guidance of the doctor for treatment. If there is an increase in tofu-dregs or cheese-like leukorrhea, accompanied by vulvar and vaginal itching and pain, it may be mycosis fungoides, and fluconazole can be taken to achieve antibacterial effect, but there may be adverse reactions such as diarrhea, nausea, and vomiting after taking it. If frothy, foul-smelling leukorrhea with vulvar itching, burning and pain is observed, it may be trichomonas vaginitis. Metronidazole tablets may be taken for anti-inflammatory and anti-infective effect, but may be accompanied by side effects such as nausea, vomiting and headache. If you find increased leukorrhea with fishy odor, accompanied by vulvar itching and burning sensation, it may be bacterial vaginosis, you can take metronidazole, clindamycin, etc., which can play the role of anti-infection, but may be accompanied by abdominal pain, diarrhea, rashes, and other side effects appear. Therefore, patients with vaginal burning sensation should go to the hospital to do routine examination of the leukorrhea, to clarify the type of vaginitis, and then take medication under the guidance of the doctor, not blindly use drugs.
