If you don't have and abnormal MRI, you don't have muscle atrophy, you have normal reflexes, myasthenia gravis is probably really high on the rule out list for a fatigable muscle weakness . I'm glad that you have an old school doctor that actually seems to know something about looking at patients and not just blood tests.
