What were your symptoms?

Hey! So although I’m going to have my colonoscopy this Monday coming up I have a bit of a nervous fear with things that I might have an IBD rather than just plain IBS so I’ve come to ask because although I’ve spoken to doctors I’ve very unsure and would like to know through other peoples perspectives especially those with IBD. How did you know it was different from the IBS? What was your pain scale and what did they use to treat it?? I have an aunt with ulcerative colitis and one with plain IBS, did you guys use any special diets as well?? Have a good evening it’s 1am here so I might not respond.
