TE, thanks. That's almost exactly what's going on with me, as I just found out. I have adhesions, which we know about, and the problems are primarily at the old stoma site.
I saw my surgeon today. My MRI was clear, but what the ER doctor didn't tell when I was there a couple of months ago, there was in fact a bit of air/fluid around the stoma site, suggestive of an obstruction. Again the ER doc did not mention this to me at all, so I'm a little miffed. This is at the old stoma site and yes, I can actually feel a bulge or hardness in this area at times as well! Interesting! My surgeon wants to see me again in 3 months. He did say that if the obstructions become too frequent or don't pass on their own, surgery may unfortunately be an option to "free up" the site as he put it. At this point, I'd have to be half dead to consider another surgery, so if I can manage these obstructions conservatively, I'd rather do that, and my surgeon agrees. So, that's where we are now. If it's not one thing it's something else, it seems.
