I understand your fear. Really, I do. But, in my totally non-medical opinion, clean EMG indicates no ALS. So, I'm leaning towards no ALS. At this point, if I were you, and for peace of mind, I'd be asking the second neuro for a referral to an ALS clinic for further investigation. Please keep in mind, that many many other most treatable conditions can and do mimic ALS. I would not be jumping to conclusions, just yet. I know it's hard, but do yourself a huge favour - Stay off the Internet for the next two weeks - and try to shift your focus to something else. It's not easy, but it's not impossible.
