Chronic dizziness can be a sign of Meniere's disease. If you have alot of sinus infections or drainage, you may be experiencing a fluid build up in the middle ear. You might want to see an audiologist to determine if that is the cause. For me, I have it fairly mildly and find that by taking something like Sudafed Plus, it clears my ear and deals with the dizziness. If it is worse, you may need something like antivert if Meniere's is the problem. One thing, Meniere's causes progressive hearing loss and tinnitis, so you want to make sure of what the problem is.
