Thanks for writing to H.C.M.
I have gone through your query regarding your sore throat
, running nose and fullness and pain in ear. I would like to tell you that you are having watery running nose which result in post nasal drip
and this drip had given rise to sore throat. Infection from throat has reached to ear via Eustachian tube thus you felt ear blockade and followed by earache.
As far as treatment is concern you are advice these basic investigations-
(1) C.T.scan of paranasal sinuses
(2) Culture and sensitivity of throat swab.
(3) Blood- CBC, ESR
, blood sugar- F & P.P.,
After this through examination is necessary to get clinical findings and their co-relation with inferences of investigations one can made complete diagnosis which later can be plan for treatment.
