Hello @tammy72, welcome to Mayo Clinic Connect. I understand the frustration of not being able to live a normal life and the need to return to work. It's good to hear you are a Stage 4 survivor in remission. You mentioned you have been referred to Mayo Clinic. I have no experience with MG but can tell you that Mayo Clinic is very good at diagnosing and treating patients. They are patient centered and the different areas work as a team to help diagnose and treat patients.

Here is some information from Mayo Clinic that may be helpful on Myasthenia gravis Diagnosis & treatment:

Do you already have your Mayo Clinic appointment setup?
