I've been trying so hard to believe that my chest, back, shoulder, jaw, and arm pains are from gas. Sometimes I burp for hours at a time. But then my stupid anxiety screams NO ITS A HEART ATTACK! I can't take it much longer. I've been fighting going to the ER for days but I get closer and closer to giving in. The jaw pain especially worries me because it's not consist and with gas. And hours of burping doesn't make it go away, not does gas x or any other stomach medications.
