Suggest Treatment For Sore Throat

I m male, 45, don t smoke.... I ve had a sore throat for a week.... no fever, no chills, no runny nose...last two days I ve started to cough when I wake up in the morning, with sputum involved.... then I feel better the rest of the day.... Had pneumonia 6 months ago; turned out it was bacterial.... Antibiotics worked ..../ that was the first time I ve had pneumonia....this feels like a much milder version.... but six days of bed rest and very little improvement....
