I had a course of 3 injections of VitB from my GP and found immediately after each injection my walking was worse. One injection each week for 3. I wobbled every where but I stuck at it. My energy levels didn't increase nor my walking. Since been diagnosed with neuropathy after a neurologist tested my nerve endings. Unable to have MRI as I have a pacemaker. Have had CT scan of head, neck and spine with nothing adverse.
