Avoid strenuous exercise after ECC scratching. ECC scratching refers to cervical canal scratching, which is used to scrape the mucosal tissue of the cervical canal with a spatula and send it for pathologic examination to exclude the possibility of malignant epithelial lesions of the cervical canal. It is indicated for abnormal vaginal bleeding, where cytology and colposcopy have not revealed any abnormality. Cervical canal scratching usually causes trauma to the cervical canal. Strenuous exercise and heavy physical labor will easily cause bleeding from the cervical canal trauma. After the operation, you should also keep the vulva clean, wash the vulva with water every day, wear pure cotton and breathable underwear to reduce the occurrence of gynecological inflammation. In order to avoid the infection of pathogenic bacteria, avoid sexual intercourse for one month after surgery. It is recommended to consult a professional doctor for specific conditions.
