Which is a sign or symptom of sinus squeeze?

• A. Intense Pain
• B. Dizziness
• C. Nasal obstruction
• D. Blood from the nose

Answer: (D)

Sinus squeeze is a pressure-related injury of the facial sinuses that occurs when air trapped in a sinus cannot equalize properly during a dive, usually during ascent. The built-up pressure damages the sinus lining and small blood vessels. A nosebleed is a direct sign of this mucosal injury, making epistaxis a clear indicator that the sinus lining has been affected by the pressure change. Other symptoms like intense facial pain reflect the tissue stress from the pressure, and nasal obstruction can occur from swelling, but bleeding provides a more specific, observable sign of sinus involvement. Dizziness is more suggests inner-ear squeeze or other decompression issues, not the sinus-specific problem.
