Hello after long visits to the doctors' offices without finding out the specific cause of the dizziness, which I received daily for 7 months. Finally I went for an MRI and found that I have: mildly reduced lumen: hypoplasia of the right vertebral artery 2-3 mm. And elastic zone 3-4 mm. in the area of the left internal carotid artery. I want to ask if someone has such a diagnosis, what is the disease itself, is it dangerous, and how is it treated?
