Hi, I have been fighting what I think started out as a cold . I had a sore throat , mild chills, low-grade fever of 99-100, and was achy. I have been taking sudafed and IB Prophin for the past few days. Now I have a dry cough, green thick mucus in the back of my throat, raspy voice, no stuffy nose, and my tonsils are mildly swollen. Do you think I have an infection and do you think I need to go see a doctor?
