Second opinions, I have a neurologist who is treating me for migraines and "severe chronic tremor episodes" about once or twice a week. MRI (from previous hospital I was admitted to after another fall; three hospital admissions since February) showing two arachnoids cysts 2 x 9 and 2 x 8 bilaterally with pressure on the cerebellum. My headaches are getting worse and he did Botox injections, haven't help yet. He has never seen the report from the previous doctor nor has he requested a radiographic CD. This is making me nervous, should I be, and get another opinion? I am having eyesight problems (could be age), sharp stabbing on the side of my head, and severe jerks even while asleep???
