Thanks for writing to H.C.M. for your query.
I have gone through your query regarding frequent sinus infection
, blood in mucus, blocked nose. After considering your symptoms and co-relating it with your history of illness for sinusitis
it appears as secondary infection is going on.
You are advice for these basic investigations-
(a) C.T.scan of paranasal sinuses
(b) Culture and sensitivity of nasal discharge.
(c) Blood - CBC, ESR
, blood sugar (F. & P.P.), serum creatinin.
(d) Urine- Routine and microscopic.
After this thorough examination and clinical co-relation of inferences of investigatins will guide us to reach to proper diagnosis which can be accordingly managed.
