I was diagnosed with mesentric panniculitis from a CAT scan. My doctor and my gastro guy do not think it is. They think it is IBS. The only symptom I have is I wake up every morning anytime between 1:00 am and 5:00 am with a mild pain or cramp in the very bottom, right side of my pelvis. I get up and walk around as it feels better. If I have even a little bit of gas pain goes away… within a short time I have a bowel movement and the pain is gone and does not come back until the next morning. Doesn’t appear that anything I eat irritates this. I have had this for over a year and before that something similar but it was sporadic before that. Does anybody else have this! Need some feedback please….
