I have a low grade fever (99.4), lots of sinus pressure, a headache, and a slight cough (worse at night). The mucous is yellowish, and I coughed up something that looked green this morning. I had a sinus infection two weeks ago and was given a Z-pack to clear it up. That worked, but now this is happening. I also woke up with lots of "goop" in my left eye, but I cleaned it with a warm cotton-ball and things are better as of now. I took 1200mg of Mucinex-D this morning and Nyquil last night to sleep.
