Ken, I am seronegative too sorry to hear ur struggling w this. I was diagnosed at Unc, and had my thymectomy there as well. My neurologist thought the thymectomy would be a smart decision as well..but I got very weak after, my mg seemed to worsen from the surgery. I was on no medication and had a few symptoms then it turned into not being able to breathe/eat/chew/swallow a few months after surgery. (not to scare you, but to help with your decision). most neuros will tell you, you may get worse before you get better w the thymectomy. it's up to you and your neuro. i am a year and a half post thymectomy and still need ivig every month, prednisone and imuran and I still
get symptoms.

please don't hesitate to ask any/all questions.
