Welcome in H.C.M.
I have gone through your query regarding fluttering in left ear . soreness in right ear, and fall in April during holidaying.
Your symptoms are in favor of recurrent secretory otitis
media with vertigo
. Most of the time it is either allergic or viral and self limiting. but you should do-
1- C.T.Scan of head.
(pure tone & Impedance audiometry).
3- Vestibular function test.
I think with the help of inferences of above investigations and findings of clinical examination one may find out the facts behind your problem and that may be accordingly manage.
