I have had a persistent cough for more than 2 months, at one point I also had cold sx, sinus issues etc early on but since then it has developed into a cough which appears to be brought on by irritation especially when I talk (my job involves talking all day on the phone) and eating, my throat has been sore for weeks and my voice is becoming very hoarse. I have had problems with loss of voice in the past due to my job but not with these other sx. I am also a smoker and am starting to worry just a little! Sometimes when I am talking to a customer the urge to cough is overwhelming and I have to mute the call, I am trying to drink water to keep hydrated because my throat feels so dry (I live in Las Vegas so I think the air is also a contributor, my nose and throat feel dry and stuffed up constantly).
