<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have had a sore throat for 7 days. I have no voice or hoarse voice for 3 days. I have a cough with dark green phlegm for 3 days as well. I have nasal congestion and a runny nose at the same time. I am fatigued and probably dehydrated even though I am drinking fluids to help my throat. I probably should have went to the DR. a couple days ago...so does it pay to go now?
