Do you have the urge to go and just can't get it out? If so, try nibbling on some of those fiber wafers or take a stool softener. I had to take those after I had my daughter cause of my stitches. The fiber just kind of helped to soften things up so you dont have to strain and should not give you watery d or cramping like laxatives.
I feel so bad for you I know how shitty (no pun intended) it feels. Hope you get some relief!
