I started with an upper left back discomfort with some reflux a few months ago. Sometimes can feel in the front and side. Now it hurts on both sides. I can feel it when i lay on my back or shrug my shoulders back. I've convinced myself its my liver or pancreas. Just had all my bloods done and all ok apart from my gamma gt was high but dr didnt seem bothered. I can't stop thinking about it. I also have diarrhoea too.
