Those don't sound like flu symptoms to me. They sound like head cold symptoms.
I'm on day 8 of these very same symptoms (and I'm ready for them to leave). It's been going around here although for some inexplicable reason I seem to have gotten worse case of it than anyone we know. It's a butt kicker.
fever - up to 104 degrees C
headache
muscle aches and stiffness
nasal discharge
cough
shortness of breath
chills
fatigue
malaise
sweating
loss of appetite
stuffy, congested nose
sore throat
