On my way to lunch at Saddlebrook, my brother called and spit out a lot of information at me. What I caught was this: there might be a stenosis of my PICA and I might have had a small dissection which caused the lack of blood flow to my cerebellum. I could have another scan (CT angiography?) of my neck which might or might not determine if I had a dissection. But even then, it might not change the treatment. I’ll bring this up with my PCP next time I see him.
