Hi. I Have Constant Pain In My Left Side. My

Hi. I have constant pain in my left side. My back left lower shoulder blade. And I my upper left chest. The chest pain is high almost to my collarbone. The chest is like I have a bruise if that makes sense. My shoulder pain is a constant soreness and my ribs constant pressure pain. I wrap my chest up and it helps. Also I make myself burp and that helps for a second.
