Hi, I had cold symptons this past weekend, nothing too bad. I started feeling much better on monday, but then monday night I started getting really bad chills, shivering and unable to stay warm. I also felt feverish, and a little nauseus as well, although I did not vomit. This continued throughout monday night and into Tuesday morning. Around noon on Tuesday I started to feel better, even though I still felt a little achy/nauseus, but nothing too bad. I feel pretty good right now, but I still have a good bit of mucus buildup in my lungs, and sinus pressure/runny nose. Should I go to the doctor, or can I ride this thing out and start feeling great by this weekend? Any help is much appreciated. Thanks!
