Thanks for the replies. How it affects me: my fingers and toes get numb and turn completly white when I am the slightest bit cold. When I attempt to warm them and return circulation, it becomes painful – throbbing and tingling – sort of like the “pins and needles” sensation I felt with GBS. Doctor does not seem too concerned. But I’ve always thought it was a residual GBS condition, due the nerve damage in my extremeties. Thanks for the advice, Judy! And, were you ever on medication (blood thinners?) for it?
