hi tatianne,
i started experiencing spells of dizziness shortly after i was diagnosed in july 2007. at first, all I had is some facial numbness, which i started feeling around march 2007. in july 2007, i was diagnosed with a 2.5 cm AN. in late july and august i started having dizzy spells that would last an hour or two, sometimes more. i was treated august 22-24 with cyberknife. in the few months after treatment, i had acute episodes of imbalance due to the inflammation caused by the radiotherapy. but thankfully, the worst of that seems to have passed. now i have a lingering but overally pretty minor issue with balance, and i am expecting that will continue to improve over time. i'm very pleased right now with how i'm feeling.
when i began having balance episodes prior to treatment, i contacted a neurosurgeon and was told the episodes would continue to worsen until the tumor was treated. in your position, i would certainly advise your neurosurgeon of this new balance symptom. generally, i believe you are better off treating your AN at a time when you are having as few symptoms as possible.
best regards,
francesco
