What is a good way to cure a fever and a sore throat as soon as possible?

Get it checked: For significant sore throat with swollen tonsils / lymph nodes – see physician & get a streph throat test. If you have streph throat, antibiotic therapy is imperative to prevent future compications. Consider tylenol (acetaminophen) or nonsteroidal anti-inflammatory medications. Saltwater gargles: mix 1 tsp salt in 8 oz warm water – gargle several times a day. Or gargle with aloe vera juice twice a day.
