I had my band in august 2014 after 6 months i had slip repositioned in February 2015 and now i have pain in my left side of my waist especially when i eat with pain in my stomach as well. Vomitting some times all day and some times no vomit. Heart burn but not always. By the way i have no fluid in my band now its empty. What could it be?? Erosion?? Inflammation?? I have sometimes pain in my port site but not too much. Thanx
