I am battling chest congestion, annoying cough, high fever with body aches and chills. What could it be?

Infection. most of these infections are viral and respond to treatment of the symptoms , reducing the fever with Tylinol 500mf ,two every four hours,increased fluid intake and rest . The cough can be treated with any over the counter cough medicine. Howe veer if after 48 hours you are no better then see a doctor as you may need an antibiotic.
