Video: Anal fissure - Dr Naseem Video transcript Dr Naseem Mirbagheri: A fissure is a tear in the inner lining of the anal canal, similar to a paper cut on your hand. This tear is usually very painful and usually results in spasm of the sphincter muscles, which are the muscles around the anus. This tear is usually caused by the passage of hard stool but can also happen after severe diarrhoea, childbirth or any other form of trauma. The commonest symptom is intense pain during the passage of stool that may last for a time afterwards, usually because of the muscle spasm.
