Lately, I don't know why my anus hurts every time I have a bowel movement, and the pain is so severe that I can't even walk comfortably. I'd like to understand what causes anal pain during defecation.

Dr. Cheng Yicheng
Pain in the anus during bowel movements may be due to the following reasons: 1. Frequently consuming spicy and irritating foods, leading to internal heat. 2. Chronic constipation. 3. Anal fissures. If the pain is severe, it is recommended that patients use polyethylene glycol electrolyte oral solution under a doctor's guidance, which can help improve the condition.
