Anal itching is a symptom in hemorrhoids, hemorrhoids cause anal itching for the following two reasons: First, hemorrhoids can lead to deepening of the skin folds around the anus, and deepening of the folds can easily cause local infection, leading to itching. Second, hemorrhoids can lead to changes in the normal anal physiology, resulting in poorly closed anus, which may cause the anal glands to ooze through the poorly closed area to the perianal area, causing anal dampness and itching. No matter what the cause of the itching is, it is clinically recommended to conservatively treat it by using medication, using potassium permanganate solution sitz bath, with Ma Yinglong hemorrhoid cream for external use, and usually pay attention to diet to keep the stool soft and fluent.
