Recurring GBS

I know GBS can recur since I have had it three times and possibly four. When I was a child my legs were very weak. I never was treated for it since there was no diagnosis or treatment in 1948. I was diagnosed with GBS in 1958, in 1989 and again in 2002. I was never on a vent. I still have trouble with steps and weakness. My doctor never did suggest I had CIDP.
