Thank you for posting your query.
If your neurosurgeon is convinced that the arachnoid cyst
is not the cause of your symptoms, you can get an ENT check up done, especially as you also have a whooshing sound in the ear.
The signs to look for, which may suggest that the posterior fossa arachnoid cyst is the cause of your problems are: early morning headaches
, double vision
, imbalance while walking, etc.
Wishing you good health,
Dr Sudhir Kumar MD DM (Neurology)
Senior Consultant Neurologist
