I was home sick last tuesday and wednesday with very similar symptoms excpet for the throwing up part. I never even felt like I was gunna throw up. I had a fever, headache, cough and i even had blisters on the back of my throat that hurt like hell when i swallowed. I was feeling better until the weekend when I lost my voice and couldnt talk for Saturday, Sunday and even Monday in school. Im pretty much back to normal now. Still cough bad once in a while though.
Maybe you have somethin similar to what i had
