Have you ever had influenza, also known as "the flu" ? 
I've had symptoms before, but I don't think I've ever had the full blown effects of the flu. I don't usually get sick.
I don't usually get sick either and so I often don't get vaccinated. But this year I got the flu and had such terrible muscle pains and fever!
Oh no, that sounds horrible! I don't usually get vaccinated either, but made the choice to this year after I had my baby this Spring.
Good choice. I will never skip the flu shot again. I got a cough with it too, and it lasted more than two weeks!
