I had a thymoma but my MG symptoms were so overwhelming I do not remember if I had other ones. I do remember having numbness in my hands and twitching in my right foot that the surgeon said was related to the thymoma and not to MG possibly because of it pressing on nerves but that is about it. I may have had other ones but they were overshadowed by MG. I did have breathing problems but that was probably MG. My thymoma was discovered after months of symptoms, because they thought I might have pneumonia. I was x-rayed and they found it. At least it got me diagnosed and treated. I am now awaiting CT scan results to see if mine has returned. Good luck with your journey.
