Thanks for writing to H.C.M. for your query.
I have gone through your query regarding cough
and sometimes mixed with blood. You are a smoker and your tonsils are also of big size. You are not clear about blood from where it is comming, is it from lungs or from tonsils ? Your ENT doctor has advice you for tonsillectomy
as you are mouth breather.
To know from where blood is comming you should do these investigations-
(a) X-Ray chest -( P.A.view )
(b) Culture and sensitivity of throat swab.
(c) Diagnostic nasal endoscopy
A thorough clinical examination of throat, nasopharynx
, tonsils, larynx
and chest and there clinical co-relation with above investigation's result will confirm the diagnosis and that may be accordingly manage.
