I don't know yet.
Normally I don't get sick, so this just came out of nowhere.

I usually get sick for a few hours if I get the flu from someone else
Last time I had a case of the flu that sucked was 12 years ago, before that not since childhood.
Don't fall for that flu vaccine crap, every person I talk to who used to do it says its the same results except when they do end up getting the flu its way worse and ends up killing people.
