From your history it seems that you might have impacted wax in your ears causing all problems.
As you have got chronic
infection in throat
this may give chronic infection in the ear,mostly in the middle ear
There may be small perforation in the drum.
Without physical exam I can say this much.
You do nasal inhalation
with balm or this type of inhalation,this will reduce congestion in throat and in the ear.yoy may put antibiotic
drops and wax dissolving drops.
ok and bye.
