Renee, Welcome and yes some of this stuff is really over whelming. I had the same fear as you. To do the Sitz Marker test you can't use any kind of laxatives or enemas, stool softners nothing as it would not make your test come out right. But it will probably hold the answers to what is going on with you, its a great test and its easy. So everyone here is here to help each other so, glad you found us, This site helped me save my own life...good luck.
