Which symptom describes a sense of fullness or blockage in the chest, sinuses, head, or nasal areas?

• A. Sore throat
• B. Rhinorrhea
• C. Congestion
• D. Epistaxis

Answer: (C)

Congestion is the sense of fullness or blockage in the nasal passages, sinuses, or chest due to swollen tissues and mucus buildup. This makes you feel stuffy and unable to breathe freely through the nose, or feel heaviness in the chest from mucus. It’s different from a sore throat (pain in the throat), rhinorrhea (runny nose), or epistaxis (nosebleed). Congestion is the hallmark symptom of being "blocked" in those areas.
