This is Dr Savyasachi Saxena, ENT speciilist from India.
The problem that you are having could be because of various causes such as ear wax
of the ear ,infection/fluid in the middle ear etc,-to name a few.
It can easily be diagnosed ,if you visit a local ENT specialist
.He would examine you in opd and would be able to tell you quite precisely what is wrong in your ear.
He might also advise for hearing test like pure tone audiometry
for better assessment.
treatment depends on the cause of blockage and would be given accordingly.
I hope this satisfies your query.
