I have a lot of stress and anxiety in my life. The stress got really bad a few months ago. I ended up in the ER with burning in my upper back and shoulders pain. They told me I pulled a muscle and sent me home. Two days later I started having the same burning in my stomach. It has been 3 weeks of non-stop gassy, burning stomach aches and I finally went to the doctors. They are doing blood tests and Upper Gi. If they come back negative she said I probably have IBS. She said anxiety and stress can cause all of this stomach pain. Has anyone ever heard of this????
