I've had a cough and sore throat for about 2 days now but all of a sudden the sore throat became so bad that I lost my voice, I'm having trouble swallowing, low fever (101.1), achy, chills, loss of appetite, runny nose, swollen tonsils, white spots of the tonsils, and grey-ish tongue (tried brushing my tongue for awhile and it doesn't change colors).
