Hi I am a 24 year old female. I started 4 days ago with a severe sore throat, high fever, teeth chattering chills, headache, terrible body aches and loss of apetite. My doctor prescribed me an antibiotic and pain medicine. Everything haas gotten worse over the last couple days. Continued fever with chills and my tonsils are swollen with pus and canker sores all in the back of my throat. I've been to the emergency room twice and nobody really has answers. In lots of pain please help
