Kim: am so sorry to hear of your problems. I also have been dealing with constant dizziness, but the only solution I have been given is to participate in PT to realign my ears and my eyes. I have a schwannoma, but the neurosurgeon says this is not the cause of the dizziness. I also feel normal only when I am sitting or lying down. I have lost night vision completely, so cannot go out after dark. Know that many people are thinking of you.
