Hi Randi,
My husband's tremors began shortly after his first surgery to remove a brain tumor. The neurologist said it was most likely from the surgery itself, but it has continued to worsen; first after his gamma knife surgery and recently since his WBR is has gotten so bad that there are times when he is completely unable to hold a drink or a pen. It has been one of the most difficult things for Bill to accept thru this ordeal. Our neurologist has given us no hope that this "side effect" will diminish, but rather expects it is permanent damage. I hope that your mother's shaking is minimal and manageable.
Love and prayers,
