** Thanks for contacting with your health concern. 1. As I m unable to examine you directly, thus my opinion taking into consideration your symptoms are: i. As there is a history of surgical procedure thus it could be a yeast infection caused by antibiotics given at that time. ii. As your age can t be deduced, thus it could be due to a certain immunocompromised condition which has to be excluded. iii. If you think your symptoms are caused by a yeast infection, you can treat it with a treatment regimen of -azole medications for 7-14 days [which can either be vaginal cream, tablet, ointment or suppository] PS. fluconazole is the commonest prescribed medicine. 2. It could be mixed vaginal infection i.e.: bacterial+fungal+ trichomonal thus you might have to take a prescribed course of antibiotic kit and antifungal medication and a medicated pessary for yourself. PS. since candidal infection is common in diabetic patients [check with blood sugar], a patient taking broad-spectrum antibiotics, patients on oral contraceptives and AIDS thus exclude the same. 3. It will be a good idea to follow up with your attending doctor regarding detailed medical history, pelvic examination, and necessary investigation. [cystoscopy, biopsy, urine cytology], if needed and also make sure to avoid: . carbonated beverages, citrus fruits, Vitamin C, caffeine, alcohol, tomatoes, and wear loose clothes.
