Acute flare-ups of hemorrhoids can also cause pain in the vulva, especially acute thrombosed external hemorrhoids, which occur below the dentate line, the area of innervation of the limb, and are very sensitive to painful stimulation, and the patient can also be accompanied by fever. Repeated episodes of internal hemorrhoids, especially stage III and IV internal hemorrhoids, can cause the nucleus to prolapse outside the anal opening, and repeated constipation stimulation can also lead to impaction and induce perianal pain, as well as perineal or vulvar involvement pain. The most effective treatment in this case is surgery to remove the external hemorrhoids, while the internal hemorrhoids can be treated with either an anastomotic loop or a local ligation. You should also pay attention to the hygiene around the anus, make a habit of eating and defecating on time, and if necessary, you can also choose to take a sitz bath with warm salt water every day to improve the microcirculation around the anus.
