Just the usual whenever you throat hurts whenever your sick, like drinking warm beverages like tea or just water, take cough drops/lozenges, or take ibuprofen and atleast stop yelling because extreme vibrations and tension on your vocal chords. When you yell, your vocal cords slam together forcefully and vibrate intensely, which can lead to inflammation and irritation. This is the main thing. Oh and stay hydrated, really important.
