Help! I'm having symptoms of blocked ear for a week from sinusitis?

2 separate problems. Although the blocked ear and sinusitis may be caused by the same virus, the 2 problems are separate and not causing each other. Rather, most likely the virus is causing nasal obstruction leading to sinusitis and the same virus may be causing Eustachian tube obstruction leading to the blocked ear. I would advise seeing an ENT doctor for help.
