HI I have seen your mail and i came to know that you are having two different problums one related to your nose and ear and other is concern with abdomen. your blocked ear is due to blocked and swollen eustechian tube (tubular connection between nose and throat),this happen due to sore throat
and this is secondary to your sinusitis
.For its management you are adviced some investigations as- (1) C.T.Scan of paranasal sinuses
(2) culture and sensitivity of nasal discharge & throat swab (3) blood; C.B.C. & blood Sugar.Beside these good clinical examination by your E.N.T.doctor is must for clinical corelation.And for your abdominal problums you should consult your physician. Thanks.
