princesa, where exactly is your UC...limited or throughout? Are you saying that you are clear in the rectum as well except with pain/etc on the right side where there's thickening?
What meds are you on at this time?
My understanding is the flex sig they did showed no sign of disease or inflammation at this time in the rectum and up through the descending colon.
A little history: I've struggled with digestive issues all my life. As a child, I frequently complained of "stomach aches" and was often constipated. An upper and lower GI done when I was about nine years old showed nothing.
In college, I was diagnosed with irritable bowel syndrome. I was a stressed out Type A going to a tough university, determined to graduate with honors. My diet was high carb, high sugar crap. I had the usual alternating constipation and diarrhea. I was sick alot and was given multiple rounds of broad spectrum antibiotics. I suffered off and on and was given antispasmodics and anti-anxiety meds for several years.
In 1999, I came down with a bad case of flu. Again, I was given a powerful antibiotic and immediately became very ill with constant cramping, D, weight loss and bleeding. A flex sig showed bleeding and inflammation in the descending colon - typical of UC. I was extremely ill. A year later, almost to the day, I was back in the ER, bleeding, etc. All very typical.
Since that time, I've worked really hard to educate myself and learn to control my condition. It's been a long road, but I haven't had any major flares - and certainly no bleeding - for years. I'm on a maintenance dose of sulfasalazine (Azulfadine), the older version of Asacol. I also take l-glutamine, probiotics and fish oil caps. I eat a mostly gluten and dairy free diet. You might call it a modified SCD. In general, I feel pretty good most of the time and consider myself to be "in remission."
This latest episode started suddenly after a splurge meal that included several things I don't normally eat and know are triggers for me. The pain was localized and pretty constant for four days. The position indicated appendicitis, but a CT in the ER showed otherwise. The following day, an endoscope and flex sig were performed and nothing was seen since neither addressed the problem area.
