Can gas cause chest pains? I've had them since yesterday but I've also been burping and passing gas more frequently then usual after I get the pains.

Yes. There are many causes of chest pain and gas is just one of them .. it's important to know what type of food you're eating , stresses in your life, other medical conditions including prescribed and non-prescribed medicines.. it would be unlikely, that this is cardiac..Stop carbonated beverages and maybe this could be caused by increase in acid..(GERD).
