Pastor Steve,
Welcome and hope you find this forum very helpful. I was initially diagnosed with only a visit to my neuro, but a followup with the tests were made to confirm the initial diagnosis. I was put on Mestinon immediately on my first visit to the neuro and had immediate results like you. About a month later, the tests confirmed the disease. I, like others, hope you can find a way to get the proper diagnosis with tests to confirm. In the meantime, you will be in my prayers that all will be well with you!
God Bless You,
Simon
