Yes, I did. It was about six months after starting with Neuro's up at Shands, and where I had gotten my MG Diagnosis. I wanted a second opinion, but quickly learned through this experience, and going to Shands that it is extremely important to seek out people who have "special interests" in MG. There aren't too many of them in Florida, but if you look on the Myasthenia Gravis Foundation web site, you'll see three main ones listed: one in Jacksonville, one in Miami, and the other in St. Petersburg.
