I am 6 years post op and live a very active life now. I had very similiar symptoms. I am so glad you finally got your diagnosis. You are not alone. Almost all of us have similiar difficulties in getting a diagnosis. I actually had a doctor tell me I had fibromyalia. Chin up you are at the beginning of a journey back to health. I can't garantee full recovery but at least some releif. It may take some time. Keep your chin up and be encouraged. There is a Chiari support group on facebook I am part of and it has been very helpful.
