MG is a neuromuscular disease, since it affects the neuromuscular junction. Any thing having to do with nerves/CNS/muscles is dealt with by neuros. Rheumatologists also handle some diseases, such as polymyositis due to the inflammatory component. MG has also recently been implicated in having an inflammatory process (HGMB1).
Wow. No way could I live without AC due to MG! Glad you're aware of the affect on the body.
