I am having severe upper back pain after I eat, and have finally figured out it comes monthly. I had a hysterectomy years ago, but was still having pain in my back when it was that time. But since my lap band surgery about 20 months ago the pain has been getting worse. I also throw up most of what i eat during this time. just wont go down. It is only when I eat. I have had a scope & an ultra sound. Nothing shows up. Has anyone else experienced this? Any solutions? Suggestions?
