Repeated clearing of throat often causes an inflammatory reaction and a foreign body sensation while swallowing. If you are clearing throat so frequently that means you have a postnasal drip , which often occurs after a severe bout of upper respiratory infection
not adequately treated.The hoarseness
may be also a result of repeated clearing of throat/ excessive gargling/or subsequent laryngitis
. The best course of action for you would be an ENT specialist
checkup.Hope you get better soon.
