Thanks for writing to H.C.MM. for your query.
I have gone through your query regarding Loss of hearing and fillness in your ear, as you are suffering from otitis externa
It might be possible that your ear drum may be covered with debris of running infection and now swelling of ear canal
is gone so good ear cleaning may help you but this should be done with caution and preferably by expert hands to avoid complication.
You have passed 10 days already and even if infection in external ear s going on than we should think for fungal infection
and it will be better to change your ear drop
to such which contains antibiotic, anti fungal and steroids
. But this change is by the concent of your treating doctor.
