Reflux

Does anybody have a baby with reflux? I think my son might. He's bottle fed and cries when I stop to burp him and after he burps and then refuses to take the bottle back for quite a while. I have to walk around and calm him down. He screams when he's laid flat and then burps when he's picked up, even if its been an hour since his last feeding. Today I've noticed him cough every now and then. Playing phone tag with the dr so just wondering what others experience while I wait.
