Essieluv, I'm in a similar situation. I was in remission for about 2 years, then about a year ago I fell out of remission. I started passing blood and having a lot of bad days. My GI ran some tests and nothing showed up, and it was his inclination to believe that I'm still in remission and that "IBS" is causing my current symptoms (he said the bleeding is caused by internal hemorrhoids). I don't think that's the case, I don't think it's IBS, I think I've been in a flare. It's been going on for about a year now and I just had a GI appointment last month. I spent over 30 mins in his office, crying and telling him that I'm not okay and that I need something to get the flare under control. He kept suggesting things like IBS meds or antidepressants and I told him no, that's not good enough. He finally relented and put me back on Entocort, but I really had to fight for it.
Unfortunately, it sounds like you're going to have to fight for some proper treatment too. It will be hard, but you can do it. I would start by writing down everything, what symptoms you're having and how severe they are and how long they've been going on for. In my experience, IBD can sometimes hide really well on test results but at the same time cause some pretty hideous symptoms. I would also write down what you'd like to propose as a plan of action for getting your flare under control - what medication you'd like to try or what your thoughts are (stem cell treatment? Surgery? Medical trial?). I went to my GI prepared to beg for Entocort as that's what got me into remission last time, and it took a lot of begging and arguing my case (I should be a lawyer at this point), but I got it and I'm starting to feel better now that I've been back on it for a few weeks. Anyway, my point is, have a plan and stick to your guns and fight for yourself - you know it's not IBS causing your symptoms, so don't let them write you off as having IBS. Good luck and hang in there!
