Hi, I have had a pain in my stomach for years now and it makes me irritable and anxious and it throbs in the lower left side of my abdomen , I have tried going gluten free cutting out alcohol and cigarettes and nothing seems to get rid of it , it is causing me major discomfort and some days I don’t want to leave my bed as it throbs and hurts that much, is there any ideas what the cause could be !!! Please I need help
