In dealership financing â another common type of vehicle financing â you get financing through the dealership. You and a dealer enter into a contract where you buy a vehicle and agree to pay, over a period of time, the amount financed plus a finance charge.
One very common cause of ear pressure is changes in barometric pressure. When people change altitude quickly, problems can occur in the Eustachian tubes and the ear can feel blocked. Many people have this sensation when they're on airplanes, and some will even feel it if they quickly climb a mountain in a vehicle.
This can block the Eustachian Tube. As a result air cannot reach the middle ear, so the pressure there decreases. When the pressure is lower in the middle ear than in the ear canal, it causes the eardrum to bulge inward. The bulging of the ear-drum can cause pain and as a result, one may experience tinnitus symptoms. So yes, I think that sinus infection can very much cause Tinnitus.
