What causes sinus induced tinnitus?
Sinus tinnitus is caused by adverse reactions to drugs such as antibiotics or antihistamines. Tinnitus Type 3 as this tinnitus type is referred to normally occurs after prolonged spells of taking antibiotics or antihistamines in an effort to control sinus infections and allergy conditions. It is the antibiotics and antihistamines that cause the mucous in the middle ear to become too thick and viscous to easily drain away through the very narrow Eustachian tubes. Because the mucous in the inner ear is now too thick to easily drain out via the via the very narrow Eustachian tubes, a buildup of mucous in the middle ear occurs. The resultant pressure in the middle ear often leads to ear infections and tinnitus.
