Just in case you think your golf swing is giving you problems, just consider this:
Are golfers particularly susceptible to vertigo?
I'm not sure about that, although there have been a few others who have suffered, such as David Duval, Peter Hanson. It's a condition that can hit anybody at any time. The golf swing did trigger my vertigo, though, and they had to find out why. When they did, that was when I could work towards a cure.
