Hi---Just a thought---Have you been checked for Lyme ?? It can acuse all sorts of crazy symptoms, including all the you have mentioned---many labs do a basic blood or spinal fluid test that will often come back negative (false)--there is a lab in CA called IGENEX that is recognized as having the most reliable results---definitelt worth checking into---you can contact them for a "kit" to take to your Dr for the blood work----
Good Luck to you---I hope you feel better------------Doug
