@judy75 You have my empathy! Anything amiss with the digestive tract is a “pain in the butt”, pun intended. I’ve not had C-diff or diverticulitis but I did develop an internal hemorrhoid during all my cancer treatment/chemo.
To answer your question, yes, an internal hemorrhoid can cause the stool to get stuck...behind the hemorrhoid. I needed some assistance by way of an enema while I was in the hospital. Let’s just say it was very effective in short order. Due to my platelets being extremely low at the time, I had to wait days for my platelets and white blood count to go up before my oncologist gave the ‘go ahead’ to my nurse. So, you can imagine my relief and many giggles after delivering what felt like a 9 pound baby. 😂.

Being at home, perhaps try a suppository or there are enema kits. Just be cautious and maybe ask the physician/NP, who has treated you for the C-diff, if this is something you can try. Don’t be embarrassed to call and ask for advice. Best of luck to you!
