I also want to welcome you to this wonderful chat room. I have found it to be full of helpful questions and experiences with MG.
I also had a very large thymoma. After experiencing a week of very strange symptoms I ended up at Emory Hospital. They performed a thymectomy but my symptoms only got worse. That was four years ago and I feel that I have been going down hill ever since.
It is interesting to read that "limpy" had a bad experience at Emory, because my experience was without question a completely horrible one. I always thought that Emory was the best hospital and it may be for basic illnesses, but not for something so rare as MG. I truly believe that Emory tried to kill me!
Keep reading and responding, you'll be pleased with the information you will gain.
