Welcome to Healthcaremagic forum
The symptoms mentioned by you are the features of laryngopharyngeal reflux
secondary to acid reflux
from the stomach into the throat. Do not worry! This is not an allergic reaction
. Drink plenty of warm water, try taking proton pump
inhibitors ( omeprazole or pantoperazole); avoid coffee, tea and fizzy drinks.
