If you have been feeling like something is tickling or causing discomfort in your throat, it could be an irritation on your throat. This irritation is usually caused by a common cold, allergies, or food particles getting stuck in the back of the mouth and then traveling down into the esophagus. Other symptoms may include a dry cough without phlegm production; hoarseness (speaking with difficulty in voice due to swelling); or pain when swallowing. If any of them persists too long or worsens over time then visit an ENT specialist.
