HI I have gone through your mail as you said that you are having recurrent pinching pain
in right ear,associated with ringing sound,these features are mainly occuring whenever you have cold,running nose and you were trying to blow your nose, you are having dull headech and twiching of right eye also,concidering all these symtoms I am suspecting that probably you are suffering from Acute rhinosinusitis with acute otitis media
,this is because your nasal infection
is extending to paranasal sinuses
which is responsible for headech,this nasal infection also reaching to your ears via eustechian tube (tubular connection between throat and ear)thus giving pain & ringing sound in your ears.All these facts can be confirmed by following investigations-(1) C.T.Scan of paranasal sinuses (2) culture & sensitivity of nasal discharge,(3) pure tone audiometery, (4) Impedance audiometery.(5) Blood- CBC, ESR, blood sugar.After this good clinical examination by your E.N.T.doctor is also very important, clinical findings of your doctor after corelating with investigations report will tell us about correct diagnosis only than one can plan for your treatment. Thanks.
