I dont know if I am just freaking out about this quesiton, but I have chest pain in the right side of my chest a little under the right nipple. The longest time this pain has lasted was up to an hour. The pain increases to the max point when I take a deep breath. I noticed that the pain seems to come about a few hours after drinking a lot of soda. When I have this pain and move around it hurts bad. I try to lay down untill the pain passes.
