Thank you for your query Bronchitis is an inflammation of the small airways in your lung. This could be associated with allergies/asthma, infection of the respiratory tract. Secretions develop in response to inflammation and infection. This helps with clearing the airways . sometimes when there is too much, it enters our larger airways and requires us to cough it out. This process and an inflammation /infection in our throat could cause swelling of the throat and associated structures (ears, nose). The middle ear is connected to the throat by the eustachian tube , one on either side (This helps to regulate pressure in the ear). The nose is connected to several sinuses (air filled pockets in our face that help to regulate voice). When there is repeated or prolonged increase in pressure in these areas (blowing your nose too hard, coughing, swelling in these areas), it can affect the pressure within the ear and result in tinnitus (ringing in the ears). Ear infections or inner ear pathology may also be associated with tinnitus. Once the bronchitis and associated symptoms are better, the ringing should subside and go away. If this does not happen or if this interferes with your hearing, see an ENT (ear/nose/throat)specialist who can quickly examine you and treat any underlying causes. . hope this helps.
