Ah, sinus infection, how did I fail to recognize your foul odor?
Spent a good part of the morning finding an urgent care center in my PPO network I could be seen at, and once all the usual paper-passing was done and orifices stared into, the doctor's opinion was that what ailed me wasn't flu but a sinus infection. So it's Z-packs, Mucinex, aspirin, vitamins, and Tylenol, less yogurt and more (chicken) soup. Other fluids to be forced are those old reliables tea and water. Also, until the swollen sinuses become less so, sleeping sitting up instead of laying down. At least I'll be sleeping. I hope.
