I am actually still a mystery - LEMS is high on the list though.. I became sick after a surgical procedure gone bad about 6 weeks after having my son.. I was sooo sick and weak for about 6 months before I completely crashed and ended up in the hospital and they started IVIG.. they don't know exactly what is wrong with me, but just know IVIG works and i have many characteristics of LEMS and MG.. with a very strong family history of autoimmune issues. so who knows!! oh, and I've been getting IVIG for 2.5 years, so I have been sick for 3 years now.. I went from running, surfing, skiing, to just hoping I can eat, walk swallow, breathe and carry my kiddos... it was so hard.. and still can be some days.. but I'm so thankful I"m still on this earth, walking, talking and working still.. life will never be the same
