Clare, This is a TECH, correct, and not a doctor? Is this person directed by a doctor?

To tell someone who is suspected of MG that they need to do more physical activity is tantamount to a telling a diabetic to eat more sugar.

Do not allow someone else to tell you what to do! This person obviously does not understand your situation.

Who is overseeing your care? A primary care doctor/internist?

I think you need to report what this person wants you to do to the doctor who suspects that you have MG.

I'm really sorry that you are not receiving optimum care as of yet. What can we do?
