I used to guess my body was acting up when there was a marked increase in activity of the colon. I am guessing that holds true for my ostomy. If I am not putting strange or troublesome foods into my body, if I begin to be overly active, perhaps my body is telling me something.
I also (very occassionally) had tell-tale cramps and noises (due to the strictures mostly)... these also seem to reappear when the disease is becoming more active. At least in me.
When I had a colon, and when the disease started to act up, I notice I always felt like I'd been hit by a truck. Harder to figure that one out now that sleep is broken up by always going to the bathroom... but I can still monitor energy levels. If I am extremely low, something else in my body is using my reserves.
If I add all this up together, I have a pretty good indication that my Crohn's is at work again. Docs usually verify with blood tests...
Others may have better, or different, experiences.
Does that make sense? That's ow this flare is feeling to me right now...but evryone is different...
Is there a difference there between what is Crohn's and what is scar tissue/obstruction? I am curious for my own education... At what point do I blame the side effects of surgery, and at what point is it directly due to my underlying Crohn's.
I also have to admit that my experience with Crohn's is quite tame compared to many so... I'm not a good test marker for anyone.
I might be able to answer your question based on my own experence with chrons, now for me I had a fibrotic stricture ( scar tissue build up) and the pain from that almost always happen an hour or so after I ate something.
the pain was always in the same place and it was a constant pain, plus I could see the bulge in my right side where the stricture was due to the swelling.
my chrons flare was a different type of pain, and it would start in the center of my abdomen and spread down and to the sides of my abdomen. the pain was more intense, and it would come and go kinda like labor pains. very sharp pain, and my knees would hurt as well.
when I would get the double whammy chrons flare plus the stricture, it was time to go to the E.R. and spend a few days at the hospital getting pumped full of steroids and flagyl..
as far as post-op scar tissue, I will have to get back to you on that one, I'm in the hospital right now recovering from surgery, spent six hours in the O.R. to get 5 feet of my colon removed which included the stricture, & to un-twist many loops of colon that were attached to each other by fistulas. I have an ostomy now, and I'm cool with that. I hope this helps you out... take care dental guy 44
