Hey, I made a post about this recently under "Left Abdomen Pain". Still have it, both to the left of my naval and under my left rib cage, towards the middle of the chest where the rib cage curves. I think its all muscular from being so tense over the last week or so, though I have had abdomen pains on and off for months. Sometimes it feels like its radiating from my back too, which of course is in bits like most people with anxiety. Its a horrible feeling, I wish my body could get a break from it so it may have a chance of getting back to normal
