Signs that an anal fissure is getting better are the appearance of a significant reduction or disappearance of pain after defecation and a gradual decrease in anal exudate, all of which are signs of improvement. In most cases, anal fissures are difficult to heal on their own because they may cause severe pain after defecation, which is difficult to tolerate. Fear of pain can lead to constipation, which can further aggravate the fissure, and so on. During the treatment period, it is also necessary to avoid spicy and stimulating diet, alcohol consumption, straining and staying up late.
