Symptomatic Crohn's

For the last few months, I have really been strugging with severe abdominal pain in the lower right quadrant (this is where I have previously had a resection) and debilitating fatigue. I have also been dealing with fissures, mucus in my stool and bouts of nausea. I am really struggling with eating. It feels almost exactly like it felt when I got diagnosed.

My GI had me do a calprotectin test and it came back completely normal. He then did a colonoscopy and found a few ulcers but doesn't believe that that is what is causing my symptoms. Has anyone been in a similar situation? What additional tests should I have him run? I am in survival mode and unsure of what my next steps should be.
