Proctalgia fugax (a variant of levator ani syndrome) is a severe, episodic, rectal and sacrococcygeal pain.[1] It can be caused by cramp of the levator ani muscle, particularly in the pubococcygeus.[2]

Presentation[edit]

It most often occurs in the middle of the night[3] and lasts from seconds to minutes,[4] an indicator for the differential diagnosis of levator ani syndrome, which presents as pain and aching lasting twenty minutes or longer. In a study published in 2007 involving 1809 patients, the attacks occurred in the daytime (33 per cent) as well as at night (33 per cent) and the average number of attacks was 13. Onset can be in childhood; however, in multiple studies the average age of onset was 45. Many studies showed that women are affected more commonly than men.[5] This can be at least partly explained by men's reluctance to seek medical advice concerning such a delicate case as rectal pain.[6]

During an episode, the patient feels spasm-like, sometimes excruciating, pain in the anus, often misinterpreted as a need to defecate. Simultaneous stimulation of the local autonomic system can cause erection in males. In some people, twinges sometimes occur shortly after orgasm. Because of the high incidence of internal anal sphincter thickening with the disorder, it is thought to be a disorder of the internal anal sphincter or that it is a neuralgia of pudendal nerves. It is recurrent and there is also no known cure. However, some studies show effective use of botulinum toxin, pudendal nerve block, and calcium channel blockers. It's not known to be linked to any disease process and data on the number of people afflicted vary, but prevalence may be as high as 8%–18%.[4][7] It's thought that only 17-20% of sufferers consult a physician, so obtaining accurate data on occurrence presents a challenge.[4]

The pain episode subsides by itself as the spasm disappears on its own, but may reoccur.[4]

Treatment and prevention[edit]

Traditional remedies have ranged from warm baths (if the pain lasts long enough to draw a bath), warm to hot enemas,[8] relaxation techniques, and various medications.

Applying ice or "blue ice" to the area has reportedly benefited some sufferers. http://patient.info/forums/discuss/proctalgia-fugax-33677

In patients who suffer frequent, severe, prolonged attacks, inhaled salbutamol has been shown in some studies to reduce their duration.[9]

The use of botulinum toxin has been proposed as analgesic,[10] and low dose diazepam at bedtime has been suggested as preventative.[11]

The most common approach is simply reassurance and topical treatment.[12]
