I just had surgery Feb 8th and also had cervical surgery about three months before . I seem to be doing o.k. Still have some headaches but they are not as severe. I have gained feeling back in my feet and I guess all over . I can feel the pain from the fibromyalgia and carpal tunnel and thorac as i felt before the chiari got so bad . hope you do well , don't be afraid , I was at first but God gave me peace about the surgery and I trusted Him to guide the surgens hand.
