My answers to your questions are:

#1 No

#2 Yes - but only right knee - but this knee has been broken and operated on 3 times...so maybe that explains

#3 Had all the tests and they were non confirming. DX'd clinically and through positive response to Mestinon

#4 EMG - I was told it was a borderline pass. Did not conclusively show abnormality.

# 5 I was tested for VGKC ab and was negative (as I was for all the antibodies)
