Hello, I can understand your concern. Open wounds and sores are always vulnerable to catch infections. In fact, as you are having so much itching and burning, you might already be suffering from bacterial vaginosis. Some sexually transmitted diseases like Hepatitis can also transmit from contamination through open wound. So treatment and healing of wound is important as it is not always possible to take care where infections will be and where it will be not. Skin is a natural barrier to protect against such infections. I would advise you to visit your gynecologist and get the diagnosis of the open sores through physical examination and further investigations. Starting proper treatment will relieve you of current itching and pain while protecting you from chances of infections in future. I hope this information helps. Thank you for choosing HCM. I wish you feel better soon! Best, Dr. Viraj Shah
