Information Overlaod on MG

  After many months of testing my doctor has told me that he is 99.99 % sure that I have Myasthenia Gravis.  To which I understand is a form of MD.  I've read a lot of information of MG and now I think I'm suffering from information overload.  Some of the info I have read says that it has to be "in" the family and other material says that it can just happen.  I live in a place where it gets very hot in the summer and becasue this past summer affected me so much I have seriously concidered moving North.  Can you please give me some more info on MG and what kinds of treatment is available.

Rather than contribute to the information overload could you please
rephrase your post in the formof a smallnumber of specific questions.We
are usually limited to a few hundred words at most and could easily fill
that space without addressing any of your specific concerns.
Also what do you mean by MD,if you mean myotonic dystrophy,MG is not related.
