Proctalgia fugax is a painful, involuntary contraction of the muscles in the anus. It can last for a few minutes and cause intense pain, discomfort, or a feeling of pressure in the anal area.
This condition can happen to anyone, but it is more common in women between 40 and 50 years old. It does not have a clearly defined cause, but it may be triggered by factors such as stress, anxiety, constipation, or intense sexual activity.
Pain in the anus should always be assessed by a primary care doctor or proctologist to rule out other causes and start the most appropriate treatment. For proctalgia fugax, treatment may include therapies that teach relaxation techniques to help prevent involuntary contractions of the anal muscles.
Symptoms of proctalgia fugax
The main symptoms of proctalgia fugax are:
-
Pain in the anus that lasts for a few seconds or minutes, but can be very intense;
-
A feeling of pressure in the anal area;
-
Discomfort when having a bowel movement.
Pain episodes are usually not very common, but some people may have painful episodes two or three times per month, for example.
Symptoms usually begin between 40 and 50 years old and should always be evaluated by a proctologist, as more serious conditions, such as bowel or anal cancer, can also cause this type of symptom.
How to confirm the diagnosis
Proctalgia fugax is usually diagnosed by a proctologist based on symptom assessment and clinical criteria that help rule out other conditions that can cause pain in the anus, such as hemorrhoids, abscesses, and anal fissures.
The diagnosis is made by considering the following criteria:
-
How often pain in the anus or rectum occurs;
-
How long the pain lasts and how intense it is;
-
Absence of pain in the anus between painful episodes.
If other causes are suspected, the proctologist may also order additional tests, such as a colonoscopy, MRI, or ultrasound, for example, to rule them out.
Possible causes
The causes of proctalgia fugax are not completely known, but it appears to be related to spasms, which are involuntary muscle contractions in the anal area.
However, proctalgia fugax may also be triggered by factors such as constipation, menstruation, stress, anxiety, and intense sexual activity. It may also occur more easily after sclerotherapy for hemorrhoids or a hysterectomy, or it may be associated with gastrointestinal changes, such as irritable bowel syndrome.
Treatment options
Treatment for proctalgia fugax is determined by the proctologist based on the intensity, duration, and frequency of the anal contractions. Treatment is not usually recommended for people whose proctalgia is infrequent.
Proctalgia fugax does not have a cure, so treatment recommended by the doctor aims to relieve pain during an episode. Although this is not yet a well-established treatment, albuterol, a medication used by people with asthma, appears to help relax the anus and reduce symptoms.
Biofeedback exercises may also be recommended. These exercises involve contracting and relaxing the anal muscles to help control sphincter spasms.
In addition, it is important to regulate the gastrointestinal tract through a balanced diet and regular exercise. In some cases, psychotherapy may be recommended to help relieve excess anxiety and tension, as episodes of proctalgia fugax can also be triggered by emotional and psychological changes.
