Sir, i am having giddiness for the past 7 years.what cud be d reason.?

Giddiness?: "giddiness" has several meanings, including dizziness & a whirling sensation in the head. Also it can mean frivolous & lighthearted. Dizziness of 7 years' duration is something your own physician needs to investigate; there are exercises to correct some types of this. Many chronically anxious people experience long-term dizziness, in which case treatment for anxiety might help.
