What Causes Anal Pain?

Anal pain is one of the most common clinical symptoms encountered in proctology. Proctology encompasses numerous clinical manifestations, including rectal bleeding, prolapse, and pain—among which pain is both the most frequent and the most complex symptom. Many anorectal disorders can cause anal pain, such as rectal or anal foreign bodies, thrombosed internal hemorrhoids, thrombosed external hemorrhoids, perianal abscesses, and anal fissures. The nature, severity, and precipitating factors of the pain may vary significantly.

In some cases, no underlying organic disease is identified; however, prolonged consumption of spicy or irritating foods may lead to transient anal pain. Another scenario is functional anorectal pain—a condition in which comprehensive diagnostic evaluations reveal no structural abnormalities at the anus or in the surrounding tissues, yet patients consistently report anal discomfort. This condition is commonly associated with psychological factors, particularly depression.
