Hi Nutmeg.. I have the same symptoms as you mentioned. I walk well at home but can’t walk in open spaces. I can walk near a wall but panic if I don’t think I can reach something stable. I walk fine if I hold onto to someone. How are you doing now? Did you continue the IVIG? Do you have type one diabetes? I do have hypothyroidism and Pernacious anemia. Thank you for posting.
