I have a 5mm Chiari, with alot of symptoms. I've been seen by the best and passed around by the rest! I have myoclonic seizures, spasms, and twitches (over 500 a day!). Trouble with my gait, lose of smell, blurred vision, head pain, exshaustion, memory problems... and the list goes on.
The one thing that seems to keep everything under control is predinsone (I also have Lupus and EDS) I'm at 35mgs a day right now, and that makes almost all of the symptoms go away.
