It certainly sounds a lot like the list of symptoms that happen when people have the good, old-fashioned flu (influenza). Definitely go to your doctor. I know you've already been sick for a while, and so it's likely already too late to try and take one of the antiviral drugs to shorten the duration. Can you take some time off till you get well? You're contagious, you see. And the flu can be deadly to older folks or people with other health issues.
