Dr. Cheng Yicheng
Mild anal fissures typically present with symptoms such as pain, constipation, and bleeding. The pain is severe and cyclical: during defecation, there is a burning or knife-like pain that disappears within minutes after bowel movement. Afterwards, spasmodic contraction of the anal sphincter occurs, causing pain that lasts for over half an hour until the anal sphincter muscles relax and the pain subsides.
