Six years ago, a PA ordered a CT scan because I was having some very mild headaches and a barely noticeable lack of balance at times. The radiologist calls and says, “Go to the ER. Your right vertebral artery is blocked and you’re going to have a stroke.”
Went in a couple days later (because I felt fine) and underwent two MRI’s, another CT, an ultrasound of my heart and some other tests I can’t remember. Spent 36 hours in the hospital with nurses checking on me every hour. Docs determined the artery was narrowed and probably like that all my life. Told me to take a daily low dose aspirin. My symptoms turned out to be sinus related.
