I don't have headaches at all.

Have you had a MRI?

A headache needs to be defined. In what area of the head does it occur? Is the pain constant or intermittent, sharp, stabbing, throbbing, dull, or any other descriptive? Have you kept a journal that describes the time of day, and the exact location and sensation you are feeling? Have you checked your blood pressure and pulse?

There are many causes of a headache. Yes, muscle weakness can cause a headache. Don't assume the cause is from MG, however.

A persistent headache requires a careful history. Did anything change 4 months ago in activity, diet, or health? Are you taking any new supplements or drugs? You really need to think thoroughly about all aspects of this topic.

A neurologist is the doctor to see for headaches. Although, depending upon the cause, a good internist can try to help determine what is going on.

Be your best advocate and write down exactly what is going on!
