As far as I know from at least one of MS affected persons, extreme fatigue is a sign of MS too. In ALS fatigue might be strong but usually in short time (weeks or so) it results in clear weakness etc. And it does not involve brainfog as far as I know, it is not a sleepiness - just a lack of willing to move or feeling that the move is extremely hard.One of my blog freinds told me about her son who was 22 - the boy spent few month literally laying in bed, he was sleepy, he might be quite absent for 20 hours per day, he almost lost his university grade, and the family decided to bring him to doctros only when he lost a vision on one eye. he was promptly diagnosed with MS, got a treatment, and recovered completely, graduated from university and works now as a stage artist in the theater...from your EMG one might probably decide that you have common issues with the ulnar nerve (who has not?). probably some trauma in toracic region and signs of once happened denervation now restoring in your glottal nerve. TwitchyMD, who is a pathoneurologist and one of the best eductated in the field fellows here told you may have axonal loss in that nerve which may rather sound like local deficite for me (like after trauma or infection)...I strongly support your idea to seek second opinion and maybe more specific second bulbar region EMG to see what is going on in your genioglossal muscle. Pseudobulbar syndrome is much frequent than bulbar ALS... by the way it also happens in MS and in several other autoimmune conditions, including Gullian Barre mentioned in the link in the above post (where the fellow twitcher had two denervation signs on EMG, lately reveresed.as far as I understand the idea of ALS clinical picture, you still lack clear and specific evidences. So do not give up.
