Welcome back to HealthcareMagic Forum,
Itching in the throat can be because of 2 reasons:
1. Acid reflux
from the stomach
2. Dryness of the throat (it can be because of less consumption of water, smoking
or excessive consumption of coffee or other sweetened beverages)
I would advice you to drink plenty of water (preferably warm water or just plain unchilled water), avoid speaking continuously for long time.
