getting over a bad sinus infection, and now that I am starting to feel somewhat better, I am experiencing heavy sweating during my sleep. I have taken an antibiotic, cough syrup and over the counter medicines in my bout with this stubborn sinus infection, or whatever it was. Did see my doctor. Said my lungs were clear at the time. I was experiencing coughing, difficult breathing, and heavy congestion. All is much better 4 week later, but now I'm getting night sweats. What's going on?
