I had a high fever 2 weeks ago (103.5) with painfully enlarged lymph nodes on my neck. I went to see a doctor who said it seemed like the flu, but the test came back negative. I left with a Rx of antibiotics and was told to take it only if I did not get better after 3-4 days. My fever improved, so I didn't take it, but as the days wore on, I developed green mucus in the high throat area, like maybe the far-back sinuses? So I started taking it, but alas, I only took 7 days of the 10 day supply. :( Maybe 3-5 days after finishing, my glands are starting to swell again, the sides of my tongue are sensitive, and I hacked up a little yellow, thick this morning... none since.
