Any time a muscle becomes weaker, there is stress on the skeletal system.

A weak muscle can cause secondary pain in MG. Weakness in area of the head from ear to ear, for example, can cause the feeling of a vice grip. That can occur after speaking or laughing. With MG, weakness is what happens after we DO something.

Maybe you could try using a u-shaped pillow while sitting. Those muscles need resting. Or more drugs.

There are many articles connecting headaches to muscle weakness. Massage can help. But massage is stimulating the muscle as well and can cause more weakness.

The odd thing about the body is that we can have more than one cause at once, thus the caution.
