Over 23 years of radio experience talkin' here...
John & Curval have it pegged...
Sore Throat (no other symptoms): gargle with warm salt water....avoid drinking ANYTHING else for at least 15 minutes.
Sore Throat + slight cough: Same as above, but 15 minutes later, follow up with 1 T lemon juice...with a 1 T of honey chaser.
Sore throat + High Fever: Go to the doctor.
Thank COD the wife of 23 years is a nurse!
