I've talked with my neurosurgeon. The type of vertigo I have is not vestibular, It is directly a result of cerebellar cancer. I had radiation both before and after the actual brain surgery and she thinks the necrosis from that is causing irritation that leads to vertigo. As the scar tissue is being reabsorbed into my system the vertigo is improving very slowly. I've been to physical therapy to learn techniques for balance but the fact is that every day when I get up I am immediately feeling as if I'm on a ship in a storm at sea. It is exhausting to live with. It may continue to improve but right now I find myself unable to live a "normal" life and do the things I'm used to. My hope is that there are others with a similar experience to share my feelings with. Maybe I can learn something about coping with this that I haven't thought of before.
