Welcome in H.C.M.
I have gone through your query regarding dizziness, cloudy ear, headache and vomiting.
Your all above symptoms are indicating that you are suffering from rhinosinusitis with eustachian tube dysfunction
leading to blocked ear and possibly labyrinthitis
. Most of the time it is viral infection but some times it is bacterial or mixed infection.
Here I would like to suggest you these basic investigations which are helpful in deciding diagnosis.-
1- C.T. Scan of paranasal sinuses
2- Culture and sensitivity of throat swab.
3- Gram's staining of throat swab.
4- ENG and Audiometry
Beside this physical examination by ENT doctor is necessary for clinical co-relation of investigations for making diagnosis.
Till above formalities are going on you may take-
1- Steam inhalation.
2- Anti histaminics.
3- Cinnarzine or betahistine
probably above will help you.
