No it should not cause you dizziness. You likely are referring to an osteoma. They usually do not cause problems especially when you've had it so long. You need to see your personal MD for a physical and evaluate your problem

It's not common. You might consider a second opinion from a retina Eye MD. I have maybe 2 in a very large practice so its unusual. They cannot be removed without damaging the retina so removal is normally not an option. The 2 that I have followed have never caused any trouble.
