I would definitely consult not just a neuro, but an MG specialist at a large teaching hospital before undergoing an operation.

I had fatigue and eye symptoms starting several years ago. I underwent 2 surgery, gallbladder first and 2 years later, hysterectomy and abdominal hernias repairs. Looking back, this was probably due to the muscle weakness from MG. Each operation left me weaker and the last one exacerbated the MG. I still have not recovered to how I felt before that surgery and not sure I will. Surgery is one of the stressors that exaccerabates MG.

Please seek an opinion from an MG specialist and good luck.
