7 weeks post op 2 level acdf and am having strange judder and vibration sensations through my body and limbs. Its very unpleasant and whilst I was having some judder sensations prior to surgery and it seemed to have gone immediately post op its now back now I am mobilising more ( I have been quite ill and havent been able to mobilise well) but I didnt have the vibrations before, they are mainly in my left arm and leg. I still have a lot of pain so am on pain relief but this juddering etc does not feel right...any experieice of this or ideas please? The juddering always felt as if it was spinal cord issue and the neuro reg said it sounded so pre op...I am guessing the vibration may be a nerve /spinal issue.?
