Well, I only just came across this term in another post here and began to wonder if that is what i'm experiencing. I sometimes experience a burning and tingling sensation (usually in my hands), have uncontrolled muscle twitches and on one or two occasions I know that i've had uncontrolled head movement too. I did a google search and from my limited knowledge this may be what i'm experiencing. I'm on Epilim so my neuro told me that the twitches may or may not be a side effect of it and isn't too worried because they remain minor. What do others think - does this sound like possible Jacksonian seizures???
