Yellow mucous ?

I have never got yellow mucous in my entire life. it has a thick consistency and it just keeps on coming. does anyone one what could be causing it ?

other symptoms i have :

- fatigue
- slight fever
- coughing
- sore throat (it BURNS )
- sore muscles (probably comes with the fatigue and how active i am when im in school)

its sooo unlike sesonal flu for me to be coughing or having a sore throat.

Sounds like flu to me, I have the same symptoms and thats what my doctor told me :/

I would recommend going to a doctor. Noone can check your condition and find the exact cause over the Internet.

This sounds however like the seasonal flu, whooping cough, pneumonia or bronchitis.
