I have been active most of my life. I first noticed something was wrong while biking. Although I had done quite a bit of vigorous distance riding during the summer, I was having trouble breathing due to a tightness in my throat. The next year seemed better, but I didn't seem to condition with hard workouts. On one 300 plus mile bike tour I had trouble breathing, and at the end of one day I was dizzy to the point of nearly crashing. I finished the tour without further incident. The next year I had periodic incidents and on two trips I had to drop out because of dizziness. Neurology!
