(proctodynia) n. pain in the rectum or anus. In proctalgia fugax severe pain suddenly affects the rectum and may last for minutes or hours; attacks may be days or months apart. There is no structural disease and the pain is probably due to muscle spasm (see irritable bowel syndrome). Relief is sometimes obtained from a bowel action, inserting a finger into the rectum, or from a hot bath, but it may be prevented by measures used in treating the irritable bowel syndrome.
