The fetus passing through the birth canal during childbirth presses against the rectum and is likely to cause an attack of hemorrhoids, resulting in severe anal pain. In this case, you can use warm water or potassium permanganate water to sit in the anus to relieve the spasm of the sphincter around the anus, which can reduce the pain. When the pain is severe, you can also incorporate diclofenac sodium suppositories in the anus to relieve pain, and then apply local hemorrhoid ointment, such as anal Thai ointment, Ma Yinglong hemorrhoid cream, etc., which can play a role in clearing heat and detoxification, reducing swelling and pain. Generally speaking, after 3-5 days of conservative treatment the symptoms of anal pain can be relieved accordingly. At the same time, improve the diet structure, try to avoid foods that are too rich in protein, and keep the stools open. If the stool is too dry, it may also induce aggravation of hemorrhoids. If the above conservative treatment options are not effective, surgery is still recommended for treatment.
