Suggest Medication For Scratchy Throat And Greenish Mucous

Currently, I am a recent college grad who does not have health insurance. I had the flu a month ago and currently I have been sick with a viral infection for a week. I have been consuming vitamin C, echinacea, dayquil and nyquil. After a week of suffering, I still have a scratchy throat and my mucus is still a greenish color. Are there any other solution besides antibiotics that can help?
