question: Got into a wreck a few years back and the doctors did a CT scan, I had a concussion of course. But the doctor was concerned because one of my arteries in my brain was twice the size than normal, and said I should consult with neurologist. Me being me though brushed it off and went on my way, but now I seem to have the shakes a little and when I try to sleep I ll shake and it keeps me up. Was wondering if this is something I should be worried about?
