Thanks for writing to H.C.M. for your query.
I have gne through your query regarding congestion on your head and blocked ears and unable to smell.
Considering your symptoms it appears that you were having cold
which later on developed to sinusitis
and giving you feeling of congestion in head. This nasal infection
is responsible for loss of smell and it progress to throat and than to ear via Eustachian tube, and finally giving rise to blockade in ear.
Thus you are suffering from ACUTE RHINOSINUSITIS WITH EUSTACHIAN DYSFUNCTION.
To treat this you have to do these investigations-
(1) C.T.scan of paranasal sinuses
(2) Culture and sensitivity of throat swab.
(3) Blood- CBC, ESR
, blood sugar- F. & P.P.,
(4) Urine - Routine and Microscopic.
After this a thorough examination and clinical co-relaton with inferences of investigations is necessary to reach to final diagnosis which may be accordingly plan for treatment.
