A couple of weeks ago I noticed that my left side of my rib cage sticks out more than the other side. I even lift my arms and suck my stomach in and you can see my left rib cage ends way lower than the right. I am a 26 year old female and for the past year I have been dieting and working out so maybe it has always been this way, and I do somewhat remember the left side always seeming a little bigger. Anyway, last time I had a physical my dr informed me that I have a slight scoliosis. Could this be the reason why I am lopsided? What else could cause this? I have anxiety so I am terrified, any advice would be greatly appreciated.
