Hello. I am a 27 year old male. For about the last year I have had this weird sensation on my left side. From my left hip up to below the bottom of my left rib cage. It’s mostly just when I am laying on my side. When I lay on my left side it feels like I am laying on something a flat piece of cardboard or something like that. It’s mostly along the hip and under the ribs. When I turn over and lay on my right side, my left side feels really tight and it is very uncomfortable. Once in awhile it will also feel like it’s back behind my left shoulder blade also. Again this has been going on for about a year now. I have had blood work and a ct scan about 6 months ago and they both came back with nothing. The feeling just isn’t going away though. What could be causing this?
