Constipation pain T9 injury

povertyflats, hi. I’m paraplegic. I use a lubricated vinyl glove to remove feces. What is your level of injury? Can you walk? Can you use your hands? We need to know a little more about you to give good suggestions. Also, I take cascara sagrada, an herbal laxative about every third day. Prune juice sometimes. Flax seed oil also keeps intestine lubricated.

Hi Forest and welcome, since that you have been classified as a complete, I assume that you have no movement whatsoever or sensation below your level of injury, if not and you do have some sensation in your lower extremities, it means that you're an incomplete.
The feeling of being constipated can vary from person to person depending on level of injury, being that your injury level gives you full use of your hands, do you self stim or do you use laxatives? There have been many people who when constipated can suffer from worse spasms. 
As r0hbart, said, the more you tell us, the more we can help

defecography (MRI with contrast agent of the bowels) could show which parts of your colon or bowels do not work properly. Defecography works like any other MRI scan. The only difference is that they fill gelatinous contrast agents into your bowels (colon). Once the bowels are filled you have to try if you can get any bowel movement. That's the way they can detect which parts of your bowels do work properly or which parts of your bowels are paralyzed.

There are several kinds of bowel management depending on which part of your bowels are affected. Some use laxatives others irrigation or suppositories. Others perform their bowel care digitally.

Knowing and understanding what is causing your constipation helps adjusting your bowel management.
