hi my name is michael. in august of 2006 i had the chiari decompression surgery and then in june of 2007 i had a cervical lamenctomy. now it is september of 08 and my headaches are back and my neck and back pain have become just about unbearable. and i am also having very bad leg pains also. what i was wanting to know is if anyone had the decompression surgery for chiari and had there symptoms come back and what was done about it if they did. it seems like the pain i am having now is much worse than before the decompression surgery. something tells me im gonna have to go through the surgery again.
