I can't say that it comes after
exertion, although tonight I felt it after
coming home from the gym - 30 min. of fairly intense aerobic exercise. However, I've had it to occur at the office. It seems - I have this impression - that it occurs when I turn my head or body to the right. I wear contacts, but this is not related to the normal problems. It is feels like it is in my eyeball.
I have been measured on occasion with high blood pressure, but generally told that I don't have a problem.
