Best wishes on the MRI results.
I just watched the movie "American Flyers" and it dealt with dizzy spells and such.
As Kevin Costner told his mom about his younger brother's dizzy spells, is that it isn't necessarily serious.
Here is hoping your outcome is the best ever.
You mention sleep apnea... do you snore heavily? My youngest son had sleep apnea, and had minor surgery to remove the uvula (is that it?) and part of the loose skin in the back of his mouth. From then on, he slept better and snored less.
Anyway, I am tired, so I am rambling.
Looking forward to riding with you soon.
