Very few symptoms

[EDS8029]

I am a 26 yr old male.  I was in Toronto for New Years and started feeling awful that night.  Was not drinking excessively.  I felt slightly feverish, very sore throat, headache.  I coughed up blood once that evening.  A couple days later, a lymph node in my left armpit swelled up, but had subsided by the next day.

I went to the doctor a day or two later, strep test came back negative.  I did not have a fever or headache.  Doctor said it was likely viral and would clear up within a week.

It is now the end of January.  All my symptoms subsided within a day or two, yet I still have a slight lingering sore throat and swollen glands in the neck.  Every once in a while, I will have a pain in my ears for a second or two that immediately subsides.  I cough up a small amount of colored mucus each morning, but my throat is not at the point where it pains me to swallow, speak, cough, etc.  My head and breathing are clear.

I am going to be purchasing a dehumidifier today, as someone informed me that a sore throat without additional symptoms could be the result of dry air.  I am also a mouth breather while I sleep.  The swollen tonsils and mucus, however, concern me a little because my body has always been able to fight off infection, and I have always been a very healthy individual.  Also, the fact that these symptoms have been lingering from a sickness lead me to believe that it is not caused by dry air.  Any thoughts/suggestions/diagnoses would be appreciated.  Thanks.
