I've been recently diagnosed with IBS. I've had relatively mild bouts with it in the past, but over the last 7 months I had a series of 3 cortisone shots for my back and noticed a gradual worsening of sx, such as nausea and cramping, sometimes to the point of losing my appetite for a week at a time. It's pretty bad at this point and has been going on for months. Has anyone else found this relationship between cortisone shots and IBS flare-ups?I should add that I've already had an abdominal ultra sound, endoscopy, CT scan, and a series of blood tests.
