From my own personal experience, this became a chronic issue for me. My first trip to the hospitald due to the pain which began under my left rib cage and extended to under my left should blade, i was misdiagnosed as possibly having pancreatitis. I was referred to a GI who erroneously prescribed medicine I didn't need. The following year the chronic pain returned and recognized the signs:pain and nausea. This time I transported from work to the hospital via ambulance. Finally a competent physician determined I had a blood clot in my liver. I was whisked into surgery where they went through an artery in my left groin and injected die to dissolve it. With all that said do not wait to long assuming it's gas.
Hi my name is Theo and I have your exact symptoms did u ever got a diagnostic a name of what it is?
