Introduction
This condition is closely associated with chili pepper irritation, as the anal region is richly innervated. Post-hemorrhoidectomy pain of varying degrees commonly occurs, especially with internal hemorrhoids located above the dentate line within the anal canal. This area is innervated by visceral nerves—not somatic (receptor) nerves—and therefore does not produce sharp or severe pain; instead, the predominant symptoms are a sensation of swelling, dull aching, and referred discomfort.
In fact, anal distension and pain have numerous underlying causes, most of which stem from disease. His condition is also quite complex; therefore, we should pay close attention to it in daily life. During treatment, identifying the root cause is critically important. So, what causes anal distension and pain?
What Causes Anal Distension and Pain?
This symptom is closely associated with irritation from spicy foods such as chili peppers. The perianal region is richly innervated, and post-hemorrhoidectomy patients commonly experience varying degrees of pain—particularly after internal hemorrhoid surgery, since internal hemorrhoids lie above the dentate line within the anal canal. This area is innervated by visceral nerves rather than somatic (sensory) nerves; thus, severe sharp pain is uncommon. Instead, patients typically report sensations of distension, a feeling of heaviness or “bearing-down” discomfort, and referred pain. Following mixed hemorrhoidectomy—which involves multiple internal hemorrhoid wounds—it is normal to experience bearing-down pain. As the surgical wounds heal, this sensation gradually subsides. However, if bearing-down pain persists or worsens, prompt medical evaluation is essential to rule out local infection.
Anal distension and pain can be alleviated through timely medical consultation and management of constipation. Upon noticing these symptoms, individuals should seek medical care promptly to diagnose and treat underlying anorectal disorders. During treatment, most patients opt for oral medications or focus on dietary modifications. A key dietary recommendation is consuming light, easily digestible foods, which supports effective management of anorectal conditions. Constipation—often resulting from dry, hard stools—can injure the anal sphincter muscles, leading to anal swelling and pain. Therefore, the primary therapeutic goal is to address stool dryness.
Dietary precautions include avoiding cold, sour, and spicy foods; limiting intake of strong tea, coffee, and alcoholic beverages; ensuring adequate rest and sufficient sleep; and maintaining bed rest when sleeping. We hope this information proves helpful to you.
