Thanks for writing to H.C.M. for your query.
I read your query regarding one sided headache,sinus infection
and ear pain
. you have also complained about pain in thumb and finger.On analysis and co-relating your symptoms it is clear that your sinus infection had given rise to headache and from here infection drain to throat thus creating sore throat
and now infection reaches to ear via Eustachian tube to develop blockade and pain in ear.
For proper treatment you should do following basic investigations-
(1) C.T. scan of paranasal sinuses
(2) Culture and sensitivity of throat swab.
(3) Blood -CBC, ESR
, blood sugar F & P.P.,
(4) Urine R & M.
After this much work through examination in necessary to find out some clinical findings and after their co-relation with inferences of investigations one can reach the final diagnosis and than after treatment may be planed .
As far as pain in thumb and one side body is concern this is a different issue for this you should consult doctor
of internal medicine.
