After taking a vacation I became ill with a sore throat and cold like symptoms, i went to the dr a week ago yesterday, got a shot and a zpack which i completed. I felt somewhat better by about tuesday but i had major congestion the whole time, that cleared up about two days ago, last night my throat started burning and hurting again, today i have acid reflux (i think) constantly nearly, which is adding to the burn in my throat and discomfort in my middle chest area, along with a very mild upper left belly pain. I am running a low fever, I feel miserable, what can/should I do?
