I feel down a set of stairs sixteen years ago and for the past year Ive had pain under my rib cage on the right side that radiates to my back.  They did an ultrasound and it didnt show any problems with my gallbladder and Ive had my appendix removed.  When I fell, my Orthopedic doctor said I had a small fracture in my back that should either fixed with surgery or I needed to loose fifty pounds.  Neither has happened.  Do you think my pain is associated with my back injury?
If there is scar tissue formation on the site of surgery done before or the fracture united smoothly both of these can cause the problems stated by you, you need to do advance test to see the area again which were treated before and after this correction ca be done if possible in my view
