I have had a bad sore throat for three days now. The first two, also fever up to 102, with glands so swollen it felt like a ball in my throat. Today, fever is gone and swelling of glands is down, but I noticed that my tongue was a light green when I looked at my throat, and the pain was hardly touched by two Motrin. I am 67. Is it possible to heal myself, or do I need an antibiotic?
