Why does black fluid flow out of the vagina

Patient's question:

No

Doctor's answer:

It may be caused by vaginitis. You need to go to the hospital for tests such as an ultrasound, colposcopy, and a routine examination of vaginal discharge. 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.
