I just drank 3 sodas in less than 8hrs, i usually drink a lot of water while I m working(janitorial work), and now all the sudden I started to feel sharp pain just beneath my collarbone in the middle of my chest, and it feels heavy to breath, more when I bend down. This also has also happened about two other times and also it was after I drank soda. So my question is, why is this happening? Is it the soda?
