Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain the symptoms of loss of hearing in left ear, vertigo, dizziness can be due to causes like like
Inner ear infection, Meniere's disease, labyrinthitis, Benign Paroxysmal Positional Vertigo, severe
motion sickness,
Cervical spondylosis,
Peripheral Vertigo etc..
I would suggest you to consult an Otolaryngologist and get evaluated and a thorough clinical evaluation and investigations like x ray, MRI SCAN of ear and cervical column, blood tests etc can help in diagnosis and treatment can be done accordingly..
You can be advised medical therapy with Betahistine..
In case of infection antibiotics can be advised..
Vestibular
rehabilitation can also be advised..
Avoid sudden jerky neck movements and take sufficient rest..
Take Multivitamin supplements..
Limit excess salt intake..
Hope this information helps..
Thanks and regards.
