Post nasal drip worsen nauseas

Anyone having post nasal drip that you kept feeling that you are swallowing mucus and the back of throat is congested with thick mucus to the point that when you want to vomit, they just seems stuck in throat and nothing comes out? Any remedies that could dissolve those mucus in throat down to your stomach? I have previously seen doctor before for flu but doctor advise to let it recover naturally without taking medication. But mine just kept getting worse.#pleasehelp #firsttimemom #firstbaby
