Welcome in H.C.M.
I have gone through your query regarding sinus infection
, sore throat
, headache and ear problem.
Considering your complaints I would like to tell you that basically you are having upper respiratory tract
infection involving you sinuses
which gradually drain to nose and than to throat giving sore throat and via Eustachian tube to ear. So the diagnosis of your disease is Upper respiratory tract infection with Eustachian catarrh.
Hope your query is explained
