It can help to see a neuromuscular specialist (that is the nerve and muscle specialist that your doctor mentioned). These are neurologists who have done extra training in diagnosing and treating disorders like myasthenia gravis. Regular neurologists can help, but patients are often referred to a neuromuscular specialist to get input and care. If your condition is getting worse, this other doctor may be able to suggest other treatments that will help. Mestinon is a good medication, but you may need more than that, and perhaps they will recommend that and help monitor it.

Take care,
