I do believe you may be onto something..,but what is causing my intercostal pain (besides gas)? I've had far less pain lately but I have noticed after a bowel movement it feels like everything is in a cramp and the space that feces were taking up is still in pain mode, like it got stretched out and can't go back to its previous state right away.
I have a hunch that phenomenon is caused by a combination of things — thicker and stiffer than normal colon walls, and a side effect of MC on normal defecation reflexes. Basically, there are two main types of defecation reflexes — the intrinsic myenteric defecation reflex and the parasympathetic defecation reflex.
You can read the details of what each type does
here.
Most of us have experienced how powerfully MC can affect both types, but we're especially aware of how it can almost instantaneously corrupt the parasympathetic defecation reflex to cause fecal incontinence seemingly at the drop of a hat.
When I originally "went through the clinic", since my tentative diagnosis was colon cancer, the first test was a series of CT scans. The scans didn't reveal any cancer, but when I questioned the operator, she revealed that my colon appeared to be stiff, the walls were much thicker than normal, and segments of it were flattened. IMO that's valuable insight that isn't commonly associated with this disease, but I have a hunch that it isn't commonly associated with the disease mostly because most people who are diagnosed do not have any CT scans, and even if they do, those markers would be shrugged off, since they're not listed as diagnostic markers of MC (or anything else, for that matter).
Normally, a BM should relieve cramps/pain (not cause them). But if the walls of the colon are thicker and stiffer than normal, then it's not surprising that the nerve sensors on the serosal surface would be stimulated anytime that a significant change occurs in the size (diameter) or configuration of the colon (such as immediately following a bowel evacuation, or partial evacuation). When this is combined with nerve sensations and physical effects of compromised defecation reflexes (because of the effects of MC), it seems logical that it should easily be possible for a normal BM to result in an inappropriate pain response, simply because MC corrupts so many normal (but relatively complex) bowel functions. As you continue to heal, that effect should fade away.
At least that's my take on the situation.
