No burps?!

Cori

My son has acid reflux and likes to hold in his burps. So tense, he doesn’t relax enough to let it out. I’ll be burping him for an hour and nothing then the second I go to set him down, he arches his back and screams. Not sure if I should be taking him to the doctor, all she’s ever done is prescribe him medicine and I’ve gone back three times needing another remedy, nothing helps my poor baby. Only thing that’s made a difference is adding cereal to help keep it down, so he throws up a little less but now he’s getting so chunky. I need more input so I can figure out what to do.
