Doctor said blocked sinus but i don't have typical symptoms. could it stil be blocked sinus?

Blocked sinus: Blockage of a sinus cavity usually leads to a buildup of mucus and this increased pressure often causes discomfort like headache or cheek discomfort. A ct scan of the paranasal sinuses would show inspissated fluid or thickening of the sinus lining. Some people with fluid in a sinus may have no symptoms. An otolaryngologist is best qualified to evaluate and advise you.
