A member asked:

Can blocked frontal and ethmoid sinuses cause lightheadedness?

A doctor has provided 1 answer

Yes: Can obstruct eustachian tube and even cause dizziness, plus the congestion feeling, and generalized lousy overall sensations. Saline nasal and sinus rinses can help, and on occasion, antibiotics break up the congestion.
