I used to be a big popcorn fanatic-- having it every night, in large quantities, and I ended up with the same issues. I worried it might be serious and have many of the same symptoms you listed, but it turned out just to be a bad case of constipation. I may have torn a little bit of the lining in my colon/intestine, but that was the worst of it, and it healed very quickly after passing all the stool in my intestine. My suggestion is to take a mild laxative for the next day or two, cut out the fibrous foods for now, and drink plenty of warm fluids which relaxes the bowel and helps move things along.
If you are worried about any intestinal damage, pick up Lily of the Desert's Aloe Vera Gel, which can be found at most health food stores. Either drink it alone, mixed with juice or water, and it will coat and soothe the intestinal walls as well as heal any cuts or scrapes.
All the best,
Thanks, Brittany, for your suggestions.
My bowels have moved regularly during this time, but I am feeling better and the worst of the discomfort has gone away. I was able to read a long thread of people who had the same problem as we've had, and most had had a battery of tests done, but nothing was usually found. As you suggested, I have been drinking aloe vera juice from the beginning and I also have been taking "Food Enzymes" and "Intestinal Soothe & Build" by Nature's Sunshine, and have been drinking warm tea with chamomile and peppermint in it. Plus I have really watched my diet and stayed away from fresh veggies, fruits and spicey food. I guess it has all helped to soothe the lining of my large intestine. But like you, I will not be eating popcorn anymore.
