The following may be symptoms of fecal impaction: 1  Being unable to have a bowel movement. 2  Having to push harder to have a bowel movement of small amounts of hard, dry stool. 3  Having fewer than the usual number of bowel movements.  Having pain in the back or abdomen.
Treating a fecal impaction involves steps to remove the impacted stool. After that, measures are taken to prevent future fecal impactions. Often a warm mineral oil enema is used to soften and lubricate the stool. However, enemas alone are usually not enough to remove a large, hardened impaction. The mass may have to be broken up by hand.
