Erin,

The logic of the Neurologists is that MG affects the Neuromuscular junction, and therefore cannot cause pain! However they conveniently overlook the result that comes when some muscle fibers are not activated. Those that are still responding are overworked in an effort to compensate. Overworked muscles will create muscle ache which is a form of pain.

I will sometimes take Advil, for the pain, but I would rather take extra Mestinon (not always a good idea) or simply rest. The best cure for overworked muscles being simple rest.

However that does mean that on a bad day I can spend most of the day resting, trying to recover from a short, slow walk to the shops.
