Hello- I just went to a gastro for the first time yesterday after my stomach not being the same after the stomach flu on Halloween of this year. I have had a complete blood panel along with a metabolic blood test and stool sample- it all came back fine. I have extreme health anxiety and the symptoms of Post Infectious IBS (which is what I've been told it is) scare me. I've diagnosed myself with horrible things (IBD... and other worse things). Anyway, I understand that my anxiety is making my stomach issues worse. I'm starting to feel better digestively but I've had low back pain- almost rectal discomfort for about a week now. The dull discomfort is similar to what I feel during my period (I get back cramps) and what I felt during contractions (obviously, a lot less painful). I've only experienced this during my period or a day or two before. My gastro said he didn't see any red flags to get a colonoscopy, but he was open to doing it if it gave me peace of mind. What do I do?
