The never-ending flu

I got a flu shot on September 22 and I've had the flu since the 23rd. Today (Oct 13) is the first day I haven't had a fever when I woke up. I have no voice, I can't taste or smell anything - yesterday I ate a lemon wedge and when I didnt get any flavor I tossed some balsalmic vinegar on my tongue and nada. My mouth appears to be made of volcanic rock.
