Well wishes and prayers requested *UPDATE*
My wife had her CT scan and all the other tests and everything came back normal. No problems found.
This is good news in that there is no tumor or other problem in her brain (other than being married to me:hand5:) but not so good news in that we still do not know why she has been having the headaches and dizzy spells and hand tremors. So, she now must see a neurologist to get some further tests done so they can find the cause of these problems.
I am relieved and still apprehensive all at the same time.
I want to thank everyone for the prayers and good thoughts that she received. They are appreciated more than you all can know! You all are a great bunch of people.
