Rectodynia, also known as proctalgia fugax, is a condition characterized by sudden, sharp rectal pain that typically occurs without any identifiable underlying cause. The pain can be brief but is often intense, leading to significant discomfort for the affected individual. It may be triggered by factors such as stress, muscle spasms, or gastrointestinal issues. While the episodes can be alarming, they are usually not associated with serious medical conditions and often resolve on their own.
