The one year I don't get my flu shot on time and I caught the flu. Let me just say it has been the most horrible two weeks of my life so advice please get your flu shot, having MS and catching this flu has been really hard. I am feeling a bit better but fever wont go away and it's strange cause know my top half of my body is feverish but from my waist down i am freezing, so i wonder why? Has anyone felt such a fever?
