can having this make you nauseated?

can having phlem in your throat make you nauseated? i try to get it out but i cant, everytime i try i gag and then i swallow it back down, its so gross, i cant sit up for long without feeling nauseated and the feeling in my throat is there, is there an easy way to get it out? yet i think i feel nauseated cause phelm or whatever is in my throat is there.. i tried soups and it didnt work, oh and i have pain all over my stomach too well mainly where the band and port is and i cant see my dr till next wednesday. just wondering if that can make you sick to your stomach/nauseated? i have really great nausea meds too but apparently i cant take them anymore cause im alergic to them. oh and i was wandering what a slippage felt like out of curiosity.
