I Have Been Sick For Over A Week Now ..

I have been sick for over a week now .. with severe cough and pretty bad pain in my lung area on the front and back of my body ... I am coughing up yellow sometimes green and sometimes even brownish mucus.. day before yesterday .. i went into this awful coughing fit and the mucus suddenly turn watery and i was coughing so bad i was choking on the mucus and i coughed up more in 10 mins that I had the whole time ive been sick. It was weird ... like something ruptured .. the mucus tasted discusting in my throat .. I know this sounds gross but almost like eggs and it smells HORRIBLE and makes my breath bad. I have had a fever of 103 but i have been controlling it with Ibuprofen. I have been in bed for day .. i just feel so exhausted. Any Ideas??
