My father is suffering from a unique issue where he always feels a pressure to pass the stool but when he sits on cupboard no stool passes through the rectum. We submitted him in the hospital & did all possible test but they did not found anything negative. Infact they did a endoscopy in that also they found nothing. Doctor have totally good remarks on his overall test but my father feel he is not ok and this potty thing keeps going on in his mind day and night. What should be done in order to found more perfect cure ?
