2. Exposure to loud noise
3. Inflammation of inner ear
or the Nerve associated with hearing
4. Systemic conditions like fluctuating blood pressure
& blood glucose levels, etc

& get a proper examination done to find out the exact cause.
Investigations like Audiometry
, Eustachian function test & estimation of blood pressure & blood sugar levels will be helpful.

There is no need to worry, you will be fine.
