The pain in the anus when eating chili peppers also depends on the accompanying symptoms, for the following reasons: a. anal pain accompanied by bleeding in the stool suggests anal fissure, which is caused by the hardening of the stool after the intake of spicy food and the excessive expansion of the skin of the anus when passing through the anus; b. pain with a small meatball outside the anus suggests the onset of external hemorrhoids, and eating stimulating food can cause local venous congestion in the anus; c. inflammation of the rectum. The pain of the anus is aggravated by the onset of local inflammation after eating chili peppers; fourth, anal sinusitis is aggravated when eating too much stimulating food; fifth, perianal abscess or anal fistula when eating improperly can also aggravate the painful symptoms of the anus.
