Yes, Danny, I get it when out running, and Dinah has it too. It is triggered by bending the head forward, however slightly. So don't look down (grin). Dinah's radiologist told her about 5% of patients get this. She and I have the 5% Club and you may join if you wish. Her doc also said it sometimes goes away, and I do think mine is fading somewhat. Bottom line, do not worry, this is not a bad thing, just a part of your New Normal.

Edited to add that if I lower my head v-e-r-y slowly, it doesn't happen.
