Dizzygirls ive been thinking of u and your daughters since I read your post. I had episodes of constant dizziness say 3 months at a time back in 2007 but one morning in 2010 I got vertigo, and have been dizzy ever since. Its only the past yr I can manage typing here more, or say reading, or looking at the tv for an hr. Mine too is concluded as brainstem dysfunction from the central nervous system. Many doctors have not been able to help. I kinda cried reading your post because I feel no one should have to deal with this. I try to keep as mobile as I can - I don't work, cant. By mobile I mean, practicing sitting up, walking about the yard. The odd trip to a shop. I do it because I afraid I I don't I ll get worse. That's all docs have advised. I have started seeing a psych to deal with it the past yr. Please give my best wishes to your daughters. I pray that they improve over time. And hugs to you too.
