Proctalgia fugax
Sudden, intense rectal pain can be frightening, especially when it comes out of nowhere. Many people experience this. Understanding what is happening can make the episodes much less alarming.
At a glance
Proctalgia fugax involves sudden, sharp episodes of rectal pain that appear without warning and usually pass within minutes. Many people describe being woken from sleep by the pain. While the episodes can be intense, the condition is not associated with serious underlying disease. The key challenge is that there is often no obvious trigger, which can leave people feeling anxious between episodes. The guides and experiences below cover what is known and what people find helpful.

- Episodes lasting seconds to around 20 minutes

Common questions
Can anything stop an episode once it starts?
There is no single reliable way to stop an episode mid-course, but people report various approaches that sometimes help. Warm baths, gentle pressure, slow breathing, and changing position are commonly mentioned. Episodes are typically brief enough that they resolve before most interventions take full effect.
Why do episodes often happen at night?
The exact reason is not fully understood. It may be related to changes in pelvic floor muscle tone during sleep. Many people find that night-time episodes are the most distressing aspect of the condition, since they are woken suddenly by intense pain.
How do I know it is proctalgia fugax and not something else?
Proctalgia fugax is a diagnosis of exclusion, which means a doctor will typically want to rule out other causes of rectal pain first. If you are experiencing rectal pain episodes, it is worth having them evaluated rather than self-diagnosing, so that other conditions can be properly considered.
