<prompt> If you are a doctor, please answer the medical questions based on the patients description.Why am I having upper left abdominal pain that radiates into my left shoulder and left mid back ?  <response>: Sounds almost like whats happening to me. Started off with abdominal discomfort for a few weeks, then suddenly I started getting back pain. Ive been to a couple doctors, and neither of them think Its anything serious. Thanks, docs...you dont have to live in this body! ; Luckily I have a CT scan coming up...but I have to wait three weeks to get it. Could be anything from muscle strain, an ulcer, swollen spleen, kidney stone...there are lots of things it could be. You didnt state your age or many other details, so this is a generality based on my existing research.
