Is it myasthenia?
While you may well have a particularly difficult-to-treat case, it is important to confirm that you do indeed have myasthenia.
If you have a positive antibody
test, the diagnosis more assured. If not, a more extensive workup might be indicated. The most sensitive electrodiagnostic test for myasthenia is a single-fiber
emg, which can be performed by a neuromuscular specialist.
