Hello Thanks for writing to H.C.M. for your query. I have gone through your clinical history regarding your sinus disease for last 4 months and fluid in ears. You have also given history of headache. On morning you find blood clot in your thrat which you spit out. Considering all aspect of your complaints it is clear that you are suffering from chronic sinusitis with recurrent pharyngitis and secretory otitis media both ears. To manage it you should do these investigations- (a) C.T.scan of paranasal sinuses. (b) Culture and sensitivity of throat swab and nasal swab. (c) X-Ray chest P.A.view. (d) Audiometery- Pure tone & Impedance. (e) Blood - CBC, ESR, blood sugar- F. & P.P. (f) Urine - Routine & Microscopic. After one should like to do examination of ear and nose and clinically co-relate with results of investigations to make final diagnosis and treatment to be plan out accordingly. With regards.
