Hello. I retired from the military a year ago after a 40-year career. I finished as a Colonel, but served as a Captain of armored cavalry during the Gulf War. I took issued pyridostigmine bromide before combat began, my unit was in the wind plume of the Sarin nerve gas explosion (verified by DOD), and organophosphate pesticides were used liberally in our sleeping and living tents for months. I was diagnosed by Mayo Clinic as having Myasthenia Gravis just a couple of months before I retired. I am wondering if there is any concrete evidence which links this pretty rare disease with exposure to the different things I was exposed to in 1991. Thanks for any information.
