I am a female age 54, being tested by neurologist for Myasthenia Gravis
with possible associated disease. Positive EMG, positive clinical assessment, sero-negative. Insomniac for 15 months when symptoms emerged. Prior to that had a nontoxic cold nodule. When I awake, in the morning and every time I awake during the night, I awake to medically confirmed non-cardiac, non-musculoskeletal chest pain. Pain seems to be consistently related to sleep/wake mechanism only.
