Chronic anal pain: A review of causes, diagnosis, and treatment

Chronic anal pain is diffi cult to diagnose and treat, especially with no obvious anorectal cause apparent on clinical examination. This review identifi es 3 main diagnostic
categories for chronic anal pain: local causes, functional
anorectal pain, and neuropathic pain syndromes. Conditions covered within these categories include proctalgia
fugax, levator ani syndrome, pudendal neuralgia, and coccygodynia. The signs, symptoms, relevant diagnostic tests,
and main treatments for each condition are reviewed.
