Thanks for writing to H.C.M. for your query.
I have gone through your query regarding clogged ear, though your problem arised due to loud noice. You have already been examined by an ENT specialist
and your nasal endoscopy
had also been done by expert hands.Every thing on nasal endoscopy was normal and on ear examintion slight congestion found and same had been treated also. Now your eustachian tube functions are also normal but you are still feeling loss of hearing.
After considering your history of illness and the effects of treatment you have already taken it appears , to get yourself checked by these investigations is now necessary-
(1) Pure tone Audiometery.
(2) Impedance Audiometery.
By these two investigations one can reach to correct diagnosis and accordingly treatment may be planout.
