I have been sick since last Monday, I ve had chills but no feaver, I m tired and I have a cough I also have this horrible taste in my mouth, this is something I ve never experienced befor. The taste fallows a coughing jag and it is foul. I slept two days in a row. Any suggestions on what it is and how to treat it? Runny nose, tierd, no appetite,chills off and on , no high temp. Very dark urine. No shortness on breath, lots of flew that tastes nasty.
