Spasms

If it is a motility issue called "spasmodic pouch", that is fairly common after takedown surgery.  The usual symptom, however, is rapid fire, machine gun like bursts of BMs, one right after the other, right after meals.  It can lead to sensations exactly like you describe, but they usually are experienced during these rapid-fire bursts of BMs right after meals.  The problem is completely controlled by anti-spasmodic meds like levsin, bentyl, and donnatal.  The only problem with these drugs, which are taken 45 minutes before meals and completely put a kabosh on the problem, is they can make you feel a little loopy as a side effect.  I only had to take them after takedown.  Eventually in my case, the excess motility calmed down and I did not need the anti-spasmodics. I took them on and off for a few years after takedown but haven't used them in probably 20 years now.

Although excess motility of the bowel is usually triggered by eating, I suppose that doesn't have to be the case, but in my case the spasms were halted by taking anti-spasmodic meds 45 minutes before eating.

In any event it is a somewhat common issue, which was identified quickly by my surgeon, and was easily controlled until it eventually resolved on its own as he told me it would.  Although the symptoms are concerning, it's just excess motility from a bowel that has just been surgeried and is nothing unusual and is fairly easily corrected with meds. As you may know, surgery does effect motility and dials it down completely at first, and then sometimes too far up when it returns.

Other people have said the same thing to me and they said anxiety medication helps a lot; if the spasms continue for a while maybe the anxiety medication might help.

Bentyl is another thing that can be good for it too, that is strictly for the digestive tract so that could be a great option rather than anxiety medication.

Jaydog, I experienced the same thing after my takedown. The spasms began two weeks or so after takedown surgery, and they were intense, sometimes it felt like a golf ball was trying to come out. Sounds funny, but it wasn't!  During those moments, I didn't try to hold on; I headed for the bathroom. Luckily I spent my recovery at home so access to a bathroom was simple. I remember I had 10 - 15 trips per day, sometimes every 10 minutes. I thought it was my new life, and I was worried, but it wasn't forever. My pouch matured around the 10th month or so and everything has been good since.

This won't be forever for you. Your new pouch is new, and learning how to work for you. Eat low residue / low fiber foods for a few more months. Avoid fruit peels, vegetable peels, nuts, seeds, spicy (will burn in the way out).  Anything that is insoluable should be avoided for now.  Let your pouch adjust, feed it soft soluable foods until it matures and can handle more solid foods. Eat like you are feeding a baby, just for a few more weeks. And remember that every day will bring something new and unusual for you and your new pouch. Unless you are bleeding heavily, have a fever, vomiting, or no stools or gas has passed and have cramps (possible blockage), try not to worry too much. This is a huge adjustment for the body. I didn't use a lot of medication related to the spasms or frequency except taking Imodium for a week or so, then I stopped.

Today was better than yesterday. It seems like things change every 3 to 4 days
