How it's used

Refers specifically to the anatomical cavities within the skull, though it is almost exclusively used in medical contexts or when discussing health issues. When people complain about sinus pain, they often use this term to describe the source of their discomfort, especially when pressure builds up behind the eyes or forehead.

Common mistake

Avoid using this to refer to the nose itself, as it specifically denotes the internal cavities. People often confuse the general area of the nose with these specific sinuses when describing congestion.
