Glad you are OK. I am not your internist (/IANAL disclaimer) and I usually don't comment in HN medical threads as weird opinions here, but reading HN taking a break from my work, I'll say generally unless you have some reason like a recent dental procedure to have gotten it depending on your age I'd ask to get a (non urgent) colonoscopy or at least MR enterography or at least consideration of it with a reason why not with someone who knows the particulars of your case and can give you real medical advice. CT has limited ability to pick up GI malignancy that can lead to translocation of bacteria from colon. If you had something like an autoimmune colitis that lead to translocation you would need to get treated and not all have preceding symptoms.
