If internal hemorrhoids can retract back into the anus on their own after prolapse, they generally do not cause severe pain. However, if the prolapse lasts for a long time or occurs repeatedly, and if the mucous membrane of the hemorrhoid core ruptures and bleeds due to friction from walking or exercising, this can lead to pain due to the localized prolapse. It may even lead to congestion and swelling of the local hemorrhoid core after prolapse, thereby causing inflammatory edematous hemorrhoids, further intensifying the pain. Therefore, to avoid pain from internal hemorrhoids, or for those that prolapse and cannot retract back, it is advisable to actively use medications for treatment at the early stages of prolapse. For recurrent cases, direct internal hemorrhoid ligation surgery can also be performed.
