The term 'Lump in the Throat' refers to a feeling of tightness or discomfort in the throat area. This sensation is often caused by an enlarged TONSIL or Adam's apple. The TONSIL is a small organ located at the back of the throat and is part of the lymphatic system. The Adam's apple is a lump of cartilage located at the front of the neck and is part of the larynx. Both of these structures can become enlarged, causing a feeling of tightness or discomfort in the throat area.
