No. I've had several odd systems. The two weirdest ones were:
1. On occasional bicycle rides, I'd have a period of time where every time I blinked, my vision would sort of "twist" and I'd seem to have a cone of darkness move in my peripheral vision - each lasting about as long as a blink themselves. Would tend to last for 30-45 minutes, gradually getting worse and then better. Haven't had that one in years.
2. General head discomfort during a bike ride. Would usually go away within a minute after taking off my helmet and bandana. Neither was especially tight though. Then one day it didn't go away, just better. Then over a period of weeks, it just kept getting worse. Never severe - just an annoying ache. Lasted for nearly a year I think before gradually going away. Haven't had that one for a long time either. Still get occasional light-headedness, but just for a moment each time.
