HI!... My husband has this same problem from time to time..He was told that the pain is muscular from straining too hard, Also, once constipated, the bowels tend to lock up and it can really hurt to get them moving again ( THIS is not unique to spinal cord injury's lol) Hubby has to go on a regiment of Miralax every day for a few days sometimes a week or longer to keep the bowels going. It does take some time to move, usually isn't instant however, the fast acting ones ( such as Exlax) can cause severe cramping..There was a time when none of this worked for him and he had to do an enema as well as something that you drink..it's clear and kinda looks like syrup while he was in rehab..that REALLY worked and I noticed that they sell it over the counter, not sure what it is called but it is with all the other laxatives and is in a clear bottle. Hope this helps and good luck!
