I seem to be quite a bit milder than most, at least for the most part. I was diagnosed last year pretty easily (sero-positive, thymoma, EMG).

My symptoms will vary, but for the most part are manageable. Mostly I have a lot of double vision (mostly with distance or movement now) and trouble chewing. My neck used to give me a lot of issues but it hasn't troubled me regularly for over a month now. I'll have occasional swallowing issues or arm weakness. And I can sometimes feel what some tightness or shortness of breath, but it's very, very rare and has never turned into anything more dangerous. I've never had to go to the hospital due to my symptoms.
