hey, i was diagnosed with a chiari 1 malformation a few weeks ago... this malformation had caused a build up of spinal fluid in my spinal column. After this was found out it explained many of my symptoms (shaking, headaches etc..) so last wednesday i had decompression surgery. This went very well and the pressure was relieved! Since then i have had none of my symptoms! All i have now is an uncomfortable neck, anyway just thought i would tell you of my experience.
