Foreign body sensations in throat may be subjective or there can be some pathology causing it. Inflammation of structures in throat like uvula, tonsils or posterior pharyngeal wall can cause foreign body sensation. And at times foreign objects like fish bones and other sharp organic matter gets stuck in and around the area of tonsils causing foreign body sensation. At times forceful deglutition or swallowing can lead to foreign sensation. Gastric reflux can cause foreign body sensation. Then there is a condition called globus pharyngeus which can cause foreign body sensation, anxiety, stress being the underlying cause. But before coming to any diagnosis your throat must be examined. Can you send me a picture of your throat through an open mouth?
