Can I get FFS with myasthenia gravis?

Hello I'm a transgender woman looking to get FFS in the near future. I've had myasthenia gravis for a little over a year now and its well controlled on prednisone and cellcept and I've had thymectomy as well. Is PS an option for me at all and would you operate on an MG patient. My thoracic surgeon said further elective surgeries shouldn't be a problem but I've heard a lot of people say they wouldn't operate on an MG patient. thanks in advance!
