There are many cases of anal itching in female patients. If there is perineal or vulvar itching with diseases like vaginitis, bacteria or eczema-like changes in the perianal skin can spread to the perianal area causing anal itching. The female patient herself has secretions from the perineum, which if not cleaned for a long time will also lead to dampness and itching around the anus, especially since the perineum itself is part of the lower jiao as Chinese medicine says, and is prone to hot flashes so itching will also occur. If some patients have anal pain and have had blood in the stool in the past, the possibility of anal fissure and internal hemorrhoids cannot be ruled out. At this time, the spasm of the sphincter muscle leads to the exudation of intestinal fluid, which can also corrode the perianal skin and cause perianal dampness and itching. If the itching is particularly severe, clinically you can use medicine, you can operate, if it is simple itching, you can use light salt water, pepper water to clean the perineum.
