Hemorrhoids can be divided into internal, external and mixed hemorrhoids. The symptoms of internal hemorrhoids are blood with defecation or lump prolapse, usually without pain; the symptoms of external hemorrhoids are lump prolapse and pain; the symptoms of mixed hemorrhoids are both. If there is a painful anal lump that is persistent and occurs for a short period of time, only a few days, it is mostly considered to be an inflammatory or thrombotic external hemorrhoid. Inflammatory external hemorrhoids can be seen as significant local skin edema; thrombosed external hemorrhoids can be seen as dark purple blood clots around the anus with a hard texture and hard subcutaneous nodes to the touch. However, it is also important to exclude paranal inflammatory infections or anal canal tumors. In paranal abscesses, the mass is hard, extensive and relatively distant from the anal verge, and the diagnosis can be confirmed if there is high tension, epidermal swelling and softening, and pus flow after suppuration. Painful masses of anal canal tumors, which appear for a slightly longer period of time and progressively increase in size, and where anti-infection treatment is ineffective, require a biopsy operation in a hospital to confirm the diagnosis by pathological section. If there is blood in the stool, or fresh blood on the stool paper, or fresh blood dripping after stool, or fresh blood ejected without pain, no change in stool habit, and formed or dry stool, this should be considered internal hemorrhoid bleeding. If there is dark purple blood or more frequent and unformed stools, you need to go to the hospital for further examination to rule out intestinal inflammation, polyps or tumors. Hemorrhoids and other common anorectal diseases often exist at the same time, and the location is hidden, so self-judgment can be difficult, so it is best to go to the hospital and ask an experienced specialist to check and diagnose the condition to avoid delays.
