Not as Young but New to CIDP

I am quickly approaching the 60 year old milestone, so I am not as young or resilient as you with this condition. I was diagnosed late last summer (even though I think the symptoms started in my 40s) after having abnormal lab work, nerve conduction studies, and sural nerve biopsy. My neuro is also hesitant about corticosteroids because of the side effects. He said that the treatment with the least side effects is IVIG. That is his preferred method of intial treatment. However, I have had only minimal improvement, but I realize that it might take longer because of my age.
