Thanks for writing to H.C.M. for your query.
I have gone through your query regarding Eustachian tube dysfunction
leading to blockade in ear, dizziness
, vomiting. You are also having sore throat
To manage it you should take-
(a) Antibiotic- Preferably according to culture and sensitivity of throat swab.
(b) Anti inflammatory.
(d) Steam inhalation.
I hope this will help you, if anyhow you don't get much relief than thorough examination by ENT specialist
wil be necessary for further treatment.
