The symptoms of internal hemorrhoids will not heal on their own if left untreated at the stage of internal hemorrhoids II. The most obvious symptom of internal hemorrhoids is the prolapsed hemorrhoid nucleus. Although the prolapsed hemorrhoid nucleus can be retracted automatically at this stage, without timely treatment, the hemorrhoid nucleus will continue to increase in size and become engorged with blood, transforming to stage 3 and 4. The formation of internal hemorrhoids is mainly caused by varicose veins around the anus, and this lesion can form thrombi or venous clusters in the perianal tissues, which, once formed, will continue to be congested and swollen if left untreated, and will not disappear on their own. The actual hemorrhoids are still relatively well treated at the second stage, and can be effectively cured by means of hemorrhoid suppository medicine treatment.
