What Causes Sore Throat Along With Headache And Cough?

I became ill on 12/24 with chills, cough, mild sore throat. 12/25 my temperature was below normal, head ache, cough, stayed in bed. The next day it felt like a cold. Improved within a few days. 1/3, temperature was 94 and i was freezing, cough, sore throat bacterial infection in one eye mild sore ears. Went to Med Stop, received Eye Drops and Antibiotics for 10 days. Still mild sore throat, mild sore ears, mild eye infection, dry cough. This has been going on for a long time. Do you think this is just a cold or maybe something else.
