Occasional anal throbbing indicates disease around the anus, including hemorrhoids and perianal diseases such as anal fissures and sinusitis. Hemorrhoids can cause occasional anal throbbing. Hemorrhoids are diseases that develop near the dentate line of the anus and are mainly caused by the formation of varicose veins around the anus, especially internal hemorrhoids that occur above the dentate line and cause anal throbbing due to the presence of hemorrhoid nuclei that can irritate the surrounding intestinal wall. Anal fissures can also cause occasional throbbing pain in the anal area. Anal fissures form many small fissures in the skin around the anus, and these fissures are irritated by the surrounding environment causing painful symptoms to occur. In addition, the anal sinus is located in a special place and is susceptible to bacterial and fecal infections, which can lead to hyperplasia or inflammation and pull the surrounding tissues, causing anal cramps.
