That is truly wonderful that you are being heard! Good luck with all the testing and hopefully you'll get some long awaited answers soon. Twitching can be an MS symptom, you may want to add it to your list and discuss it with the doc in December. It can also be caused by things like carpal tunnel and overuse of the hands with repetive motion, like typing a lot. Good luck and I'm glad things are moving for you now, let us know when you find out anything!
