Patients who experience itching and yellowish water in the vagina are mostly caused by inflammation inside the vagina. This clinical manifestation occurs due to the growth and reproduction of bacteria, or trichomonas, inside the vagina. If trichomonas is present, the patient will also experience a very strong fishy odor from the yellow water of the vulva, and some people may even experience painful urination. Therefore, after this symptom is found clinically, it is important to go to the hospital for a routine leucorrhoea examination. It depends on what pathogen is causing the problem and treat it with medication according to the type of pathogen. During the process of treatment, you should never have sex and pay attention to the cleanliness and hygiene of the vulva.
