I have a sneaking suspicion that I have a sinus infection. I've been sick since Jan. 14 but was feeling great from Sunday until yesterday. Then, This a.m. I woke up with a bad headache (temples, face), sore throat, plugged ears, and glands so swollen I can hardly turn my head. So I can't tell if it's a new cold or a sinus infection from the previous cold... can any sinus infection veterans give me a diagnosis? Don't worry, I have a dr's appointment later today I'm just curious if it sounds like an infection.
