Hi. I ve gone through your query and I can understand your anxiety. Vaginal Thrush might be due to candida / yeast infections & spreads through sexual intercourse. Also stress plays a major role. Women who tend to take poor diet, compromised immune system leading to diseases (diabetes & HIV) , sleep deprived, illness etc are at high risk. I would advice you to, 1. Maintain good hygiene and wash your vagina with soap warm water regularly. 2. Avoid feminine products 3. Use soft cotton undergarments 4. Candid B V gel . It s very effective for yeast infection & will be cured in 7 - 14 days. Hope I have answered your query. Let me know if I can assist you further. Take care. Regards, Dr. Yogapriya V, General and family physician.
