Hey everyone. I had a runny nose and a cough for a while...now I just feel like I have phlegm stuck in my throat and right above my lungs...I try to cough but it seems so thick sometimes.....When I swallow hard it seems to produce more phlegm like behind my nose..and then it gets stuck again. Is this allergies? Thanks! I have tried a nasal spray and like 3 different allergy medicines..how long does it take for allergy meds to kick in?
