i have been getting a pain in the center of my chest right at the bottom of my sternum, it comes and goes but today it isnt going away, if i push on it i feel like i am going to puke
any ideas what it could be? gas pain? acid reflux? anyone have any ideas

and its in the center, not off to the left or right, its just in the center all the time and thats the only part that hurts
Update: i also have been a little gasy, after passing gas it still hurts, not as bad though
