A 44 year old man presents to primary care with a four week history of severe, intermittent episodes of anorectal pain, each lasting for some 10 minutes without pain between episodes. Symptoms persist despite use of over the counter medications.
Anorectal pain is common, with an estimated prevalence of around 7%. It can usually be managed in general practice. However, presentation may be confounded by embarrassment and fear of serious pathology, requiring a sensitive and focused approach. In this case, the most likely diagnoses are anal fissure, haemorrhoids, or functional anorectal pain (chronic proctalgia or proctalgia fugax). Less common possibilities are listed in the box.
Functional anorectal pain occurs in the absence of any pathology; it is relatively common, affecting about 18% of patients with anorectal pain, but can be disabling. Chronic proctalgia is defined as chronic or recurrent pain or aching localised to the anus or lower rectum, with episodes lasting ≥20 minutes. The pain in proctalgia fugax lasts from seconds to minutes, without pain between episodes.
