I was 59 yrs. old when diagnosed with GBS. (15 years ago). I never had any reversal. Paralyzed from the neck down.
What I find curious about the diagnosis is that everyone I have contacted that had GBS had some measure of improvement. I was taken to the hospital upon noticing the first systoms or within an hour or so. It came very suddenly while feeling fine, no fever, no pain, no tingling. But I had a problem with diarrhea two weeks before that.
My paralysis never got any worse, or any better. Was finally intubated. Was on ventilator for 8 months.
I found it curious that with all my exposure to heavy metals, DDT,Warfare agents, and Agent Oraange, plus an old diagnosis of Scalenus Anticus Syndrome with and a rib during my twenty some years as a Navy Medic, that
the doctors never called an specialist on GBS or made any chemical analyses.
