I seemed to have a nice little three-week streak (no pun intended) of no fissure activity. Last week, I went through a couple of rough constipation days. On one particular day, I was straining pretty hard...but no stool came out. Sure enough, a quick wipe showed some blood on my typical fissure spot.
I guess when I thought of fissures from constipation, I typically thought they came after large or rough stools. But can tough straining alone cause a retear?
