Feels like i have phlegm stuck in my throat. i don't smoke.i also burp all lot not because of over indulging food. should i be worried?

Maybe you should...: When taken together, globus sensation & air swallowing with resulting belching are consistent with stress/anxiety, but from here we can't rule out GERD, dysmotility, or even atypical cardiac pain. You did not provide us your age relative to age-appropriate risk factors for the latter. If any doubt or you know yourself to be at risk, please get checked.
