Is it possible to have no inflammation in test but active UC?

Hi is it possible to have UC symptoms but zero inflammation seen in ESR(8)And CRP(13) with repeated tests from different labs( to rule out possibility of incorrect test report )?
I am having pain in sigmoid colon in morning before passing stool which I believe happens due to pressure caused by huge bulk up of stool stored in that area and also have pain in rectum and even there is swelling in rectum sometimes when I eat little bit spicy . Also have other symptoms.

Is it possible to have 0 inflammation and active UC symptoms ?

Back in August you were complaining about some of these symptoms. Quincy had suggested upping your meds, you were on low doses. Did you get your dr to increase your meds?

Those two tests are not reliable at all, my gi does not order them because inflammation can be anywhere in your body.
