I have also been suffering with this horrible condition for three months.
For what it's worth - do not see ENT they only know the basics. You need to see a neurotologist who will specialise in the balance problems caused by inner ear disorders. You should not do any rehabilition exercises until you have a correct diagnosis, as some conditions can be made worst. When you have had a full set of balance tests carried out then they will give you some exercises based on your particular problem. ie. which ear etc.
Hope this helps.
