What's the best way to get rid of a sore throat from screaming?

Stop screaming !: Misuse of voice , can give laryngitis , leading to vocal cord nodule , polyps. You know the cause so just calm down giv rest to the throat and you will be fine .

Rest it.: "Speak softly and carry a big stick; you will go far!" as Teddy Roosevelt said. Speaking softly allows the voice and throat to rest. You can also try analgesic lozenges or spray used for sore throats (generic Chloraseptic or Cepastat spray or lozenge forms). Warm salt water gargles may soothe, too. Don't exceed the dosage on the package for sprays or lozenges, or you can actually cause soreness
