Meniere's Disease Support Group
Meniere's disease is a balance disorder of the inner ear. The symptoms of Meniere's are variable; not all sufferers experience the same symptoms. However, "classic Meniere's" is considered to comprise the following four symptoms: Periodic episodes of rotary vertigo, hearing loss, tinnitus, and a sensation of fullness or pressure in one or both ears.

The dizzyness is part of the treatment, mainly because you now have extra fluid in your inner ear chamber. This should clear up in a day or two once the steroidal drop absorbs into the inner ear. This whole treatment is based on the theory that Meniere's is an autoimmune condition. This has not been proven to be a fact in all cases. Also ask the doctor what kind steroid he is using, if it is Gentamicin then there maybe some side effects your doctor should have talked to you about. There is a ototoxicity componate to Gentamicin treatment. This would explain your symptoms also.
