Flu?

Ok I got the flu shot in October.

I've had a general "crud" for 2 weeks. Nasal congestion, green snot and a dry cough.

Wednesday I went to hug one of my friends at work who'd been absent, only to then tell me he'd been home with the flu and still felt awful.

I finally went to the doc Friday. He says I have a sinus infection, and gives me an antibiotic for it called Ketek.

I woke up Saturday with a fever. I slept it off, took tylenol. Went to a friends gathering Saturday night (I know, I should have stayed home). I got back feeling achey again, took my temp and it was 100.3 I covered up, got comfy, slept and so on.

Today I am still running temps and sleeping a lot. My skin aches, my joints hurt, and I wake up with a searing headache. I'm not going to work tomorrow, I'm still taking my antibiotic, but it doesn't seem to help. I'm starting to think this isn't so much a reaction to the antibiotic, but that I have the flu??

Can I get the flu even if I had the shot? (and had no reaction to it) Will it be shorter?

Grr two more days of school left, and I can't believe I can't shake this or get better. I usually don't get high fevers, so it's the only way I know whatever's goin on is serious.

Any thoughts?
