Please ask the expert, every time I have sex, my vagina is very dry, is this a disease? Can it be treated?

Patient's question:

Approximately 8 years of vaginal itching with white discharge

Doctor's answer:

It may be caused by vaginitis. You need to go to the hospital for tests such as ultrasound, colposcopy, and routine leukorrhea examination. Local use of metronidazole suppositories and nystatin suppositories should be alternated, and oral medications such as amoxicillin-clavulanate potassium and fluconazole capsules should be taken for treatment. Pay attention to local hygiene and prevent cross-infection.
