Levator syndrome
MONDO:0023628Levator syndrome is characterized by sporadic pain in the rectum caused by spasm of a muscle near the anus (the levator ani muscle). The muscle spasm causes pain that typically is not related to defecation. The pain usually lasts less than 20 minutes. Pain may be brief and intense or a vague ache high in the rectum. It may occur spontaneously or with sitting and can waken a person from sleep. The pain may feel as if it would be relieved by the passage of gas or a bowel movement. In severe cases, the pain can persist for many hours and can recur frequently. A person may have undergone various unsuccessful rectal operations to relieve these symptoms.
Also known as: levator syndrome, painful spasm of anus, anorectal spasm, levator ani spasm syndrome, levator ani syndrome, paroxysmal proctalgia, proctalgia fugax, psychogenic anal spasm
