Five days ago I went to a concert and after that I started to lose my voice a bit. After three days of rest and lots of water, I noticed my voice was still becoming more and more hoarse. Yesterday, I suddenly developed a fever (100.8), moderate headache, head congestion (enough to hurt my ears) and moderate body aches. As a teacher, it was enough to leave school. I ve been treating with NyQuil but it doesn t seem to be getting better.
