I'm sorry to hear that. The final treatment for an anal fissure is surgery. It's a minor procedure that will stitch back the torn muscle. Take a high fiber diet including fruits and vegetables with peel. Take lots of water and make sure your stool isn't hard to avoid feeling pain. Consult a gynecologist asap.
