The main clinical symptom of mycosis vaginalis is itching of the vulva and vagina. If a patient has mycosis vaginalis but does not feel itchy, the main consideration is that the number of mycobacterial infection is small and the symptoms are mild enough to cause obvious clinical symptoms. Because a part of mycobacteria may be present in the normal vagina, but due to the small number, it does not show obvious itching symptoms, and the mycobacteria are only seen in the smear of secretions. Such patients also need treatment, otherwise delaying the treatment will cause the condition to worsen, and the increase in the number of mycobacteria leads to a large increase in secretions that adhere to the vaginal wall, which in turn causes more obvious itching symptoms, thus causing The increase in the number of mycobacteria leads to a large increase in the amount of secretions that adhere to the vaginal wall, resulting in more pronounced itching, which can cause bleeding from the vaginal wall or discomfort in the vulva or vagina. Therefore, when the discharge is tested for mycobacteria, it is also important to actively intervene in the treatment.
