I was thinking of diverticulitis regarding the low fiber diet, which is temporary when the colon is inflamed. Sorry. Fiber is necessary for adequate digestion. Do be careful with certain foods such as seeds, nuts, and popcorn, as they can lodge in the pouches (diverticuli). That is good that your symptoms have regressed. If the right-sided pain doesn't go away in a day or so, you might contact the doctor. You want to rule out an infection or inflamed appendix.
