Hi Ibo615, Thank you for your response. I am a 40 year old female. I have had burning and pain in feet for 9 month and have had a feeling of unsteadiness in the last four month. I do not have spinning vertigo, but I feel unsteady all the time. Just want to know if you have similar symptom? I have had six dose of IvIg in last two month. I feel a little bit better after IvIg, but not very dramatically. Also Just was curious if you visited the Mayo and what they have told you. I would be thankful if you respond.
