Some more questions regarding UC...

I figured I'd just start a new post with all my questions. My background: 27/f, diagnosed with UC in '13 by biopsy and blood test. UC meds: Delzicol, Pantoprazole, Canasa, Zofran, and Hyoscyamine. Vegan diet, little sweets or alcohol. Former smoker, quit '13 before diagnosis.

1. Can you have normal colonoscopies with IBD? My last two have came back perfectly fine (remission?), yet I still have symptoms. Even when I was going through a flare last year they looked good.

2. What pushes you go to the ER? What do they do for you? Anytime I've went, they've just given me pain meds and sent me on my way. No tests. Shouldn't they be doing more?

3. Does anyone else feel tired all the time?

4. My GI doesn't seem too concerned about my chronic constipation, and keeps saying my my symptoms are related to IBS, not the IBD...but no one else I know with IBS feels this kind of pain. Suggestions?
