If the examination is too painful, you need to explain to the examining doctor in time, who can lubricate the dilator with saline to reduce the pain. The common reasons are as follows: 1. Emotions of the examiner: If women are too nervous, anxious, fearful and other bad emotions in the process of leucorrhea examination, it will cause the vaginal muscles to contract, which will lead to painful examination; 2. Vaginitis: If women are suffering from vaginal inflammation, the vaginal wall is congested and edematous, when the dilator is placed to open the vagina, there may be a more serious stinging sensation, or a foreign body feeling. The patient should be careful after the examination. Patients should pay attention to the cleanliness of the vulva after the test, follow up and observe the test results, and actively treat the patient. If the test results suggest vaginal inflammation, symptomatic treatment should be given according to the type of vaginitis. For example, vulvovaginal pseudomonal yeast can be treated with metronidazole under the guidance of a medical professional; bacterial vaginosis is treated with metronidazole, but also with tinidazole or clindamycin; trichomonas vaginitis is mainly treated with nitroimidazoles, such as metronidazole and tinidazole; atrophic vaginitis should be treated with estrogen supplementation.
