For about a week now i have been fighting a sore throat. It started out sore on the left side with my left ear hurting too. After 2 days, my left side was fine and the pain moved to the right side. Another 2 days and back to the left side....and so on. I have also been coughing a lot, and have nasal congestion usually just in the mornings and evenings. Anybody have any ideas what this may be??
