Anal fissure, as opposed to the fissuring of anusitis , is usually a single split in the skin and has the typical symptoms of a tearing or cutting pain during a bowel movement, and an itching irritation typically one half hour later.
It is an acute fissure if present for less than 3 consecutive months, and after that it becomes a chronic fissure and requires a minor procedure under local anesthetic which usually cures the problem immediately and permanently.
It takes less than 3 minutes to complete this procedure in the clinic. A trial with an ointment which relaxes the tip of one of the sphincter muscles, which is in spasm, is sometimes successful — but it may only be temporary.
