r/aneurysm

Had a letter today detailing that a recent CT scan found that I have a vertebral aneurysm, not a subarachnoid one. My doctor called and explained that it is at the back of my head and in a circle of Willis. I did have a wee google at what this was but it was way over my head. I've been referred to another hospital who specialises in brain stuff and wondered if anyone has any words of advice.
