I am 18 and a few days ago I either got the stomach bug, food poison, or had acid reflux, still can't choose which one it was. I threw up all night and now 2 days later, ever since if I slightly touch my stomach(right below rib cage) on the left and really all over it hurts and I feel very nauseous. I am not bloated there and when I breath in deep it hurts and laying down triggers it. Last night I had this feeling of being starving like everytime I ate my stomach remained to feel hollow and empty and didnt gain weight from the food. I'm just concerned and annoyed with my body I want to feel like me again instead of sick.
