If you had muscle atrophy in your calf . . . and it was due to ALS . . . then you would have weakness. I assure you that the neuro who conducted your EMG placed the needle in the correct spot to look for denervation. I don't know what else I can tell you that I already haven't. It is up to you to get rid of these unwarranted ALS fears, because you simply will not listen to anyone else.
