I am trying to determine if a doctor s visit is warranted or not (viral vs. bacterial). About a week and a half ago I began developing symptoms of a sinus infection (I have a severely deviated septum and these are a frequent occurrence) and these symptoms peaked on Wednesday, along with malaise, headache, and exhaustion from inability to sleep, but no fever. My nose became extraordinarily runny as well (mixture of green and clear). Today, Thursday, I felt better, but still had a running nose and congestion (though not as bad) though now I am coughing and feel congestion in my upper chest. (Like the last time I had an upper respiratory track infection.) Every time I lay down I cough like a crazy person, and cough stuff up. When I m sitting or standing symptoms are relieved. Can it be determined if this is viral or bacterial?
