Hi Joe,
I'm very sorry to hear you lost your mother to this disease. I can understand your fears but unless the disease runs in your family, you are at no greater risk of getting it than anyone else. As most cases of the disease are sporadic. If your Mom , is the only one in your family ever diagnosed , you have no greater likelihood of developing it than anyone else.
My husband has ALS and we have 2 children - neither of them are at greater risk of getting the disease because he is the only person in his family that has ever had it.
If they did an EMG and it was clean, that is a very good sign. And it should be reassuring to you to hear from your docs that they do not feel you have ALS,
If anything feels like it is getting worse or you feel as you have real loss of strength , slurring of speech, or episodes of falling , you may wish to seek the opinion of an ALS specialist. But try not to worry in the mean time about the 2nd EMG you are waiting on . As cramping and twitching occur in many healthy people too, especially in avid exercisers.
