Feel like always have to clear throat. May something be wrong? How can I fix that feeling or irritation.

LPR . Laryngopharygeal reflux is when a small amount of acid comes up into the throat and irritates it. It is a common cause of dry tickle cough, chronic sore throat, lump in the the throat , post nasal drip, phlegm in the throat, and throat clearing. Many studies show it responds best to proton pump inhibitor Rx like Nexium, Protonix, Dexilant, (dexlansoprazole) and others. See ENT MD to do fiberoptic exam and diagnose.
