Can rectal area soften any hard stool? Inspite of regular exercise, high fiber diet, fruits, vegetables and lot of water but yet occasionally I get hard stool and as I have a tendency of anal fissure occurrence so every time when stool is difficult to pass, I get anal fissure which is very very painful. Though I take cremaffin 30 ml when occasionally stool becomes hard but it can not soften already formed hard stool, so please tell so that if occasionally stool becomes hard still anal fissure do not occur?
