Winnerhoffer will give you a massive bill but little else
joseghamby - the eustacian tube runs from the MIDDLE ear (inside the ear drum) to the throat. It gets swollen with infection and closes up. This is otitis media.
Ear drops outside the eardrum will treat otitis externa - infection of the ear canal - but cant pass into the middle ear.
The symptoms of otitis media are normally reduced hearing and fullness of the ear. The conventional treatment for middle ear issues is antihistamines and antibiotics. Some people have pain and need pain killers.
So if your symptoms dont settle go back and see your doctor, or ask to be referred to an ENT surgeon. A hearing aid wont clear it up and normally isnt needed
Good luck
