Dizziness -off feeling for over year. several tests no cause . also weakness any ideas?

Neurologist: It isn't normal for a 47 year old female to be off balance for over a year. The term dizziness is not specific. Is it vertigo (spinning) or loss of balance? If the off feeling is unsteadiness, i would recommend a neurologist. However, unsteadiness is non-specific and could be due to a number of medical problems such as thyroid disease, hypotension, low blood sugar. Also see your internist.
