I'm still on my diagnosis journey...if everything is negative, how did the doctor decide it was still MG? I get the feeling that my doctors (and I've seen 3 neuros who all keep bouncing me around) don't have a clue why I would have symptoms and not test positive. I am an epidemiologist and and I understand the numbers and percentages; I'm not sure how much they put credence into someone's symptoms without some kind of medical sign. It makes me feel like I'm crazy, but why would someone fake increasing weakness/fatigue? I like to run! I like to be active! Why on earth would someone fake this? And how? I'm looking to hear from someone who may have been through something similar. I need some support.
