I had mine out for some time, I think it is stress related because when i go on vacation the problems go away. My problems are flattened stool, long think stool, twisted stool, having to go to the bathroom every hour for 3 to 4 hours. Ive gone to a few Gastroint dr. and its useless, even got scoped! Try different foods, try to go on a Gluten Free diet for 10 days (dont stop after 2). Sometimes this helps, if it was a wheat based product that caused the blockage that caused the appendics to go, your body may have formed antibodies that are fighting it. If you avoid gluten for about 2 to 6 months, those antibodies should weaken or dissapear! Ive gone about a week without gluten, but i always fall of the wagon, its hard!
Try to relax, go on vacation and take it easy, it really helps.... Also try doing situps, about 25 to 100 a day until your abs regain strength, they pump your internal cavity with CO2 and it stretches the muscles, and basically puts them in shock! The most important thing is to not get depressed!
